WACKER makes VINNAPAS VAE dispersions, which are polymer binders made from vinyl acetate-ethylene (VAE) copolymers. These binders help make many products work better and be more eco-friendly. WACKER is the top producer of VAE dispersions and redispersible polymer powders. You can find their products in lots of areas like coatings, tile adhesives, exterior thermal insulation systems, self-leveling screeds, interior plasters, paper coatings, and adhesives.

What are VAE Copolymer Dispersions?

These copolymers are created by mixing vinyl acetate, a hard monomer, with ethylene, a soft monomer, through emulsion polymerization. The ethylene adds flexibility to the VAE dispersions, so they don’t need extra plasticizers.

Great Rheological Properties

VINNAPAS dispersions that use polyvinyl alcohol (PVOH) are easy to work with for many adhesive tasks, like paper and packaging (VINNAPAS 706 & VINNAPAS 710) . They’re good for different application methods too, such as roller and spray coating(VINNAPAS EP 705 A).

Reduced Migration

The special makeup of the copolymer means that we don't need plasticizers or film-forming agents in products with VAE dispersions. This opens up many options for making low-migration adhesives.

Improved Workability

Dispersions made with surfactants usually have better shear-thinning properties compared to those made with polyvinyl alcohol. This leads to better sticking to plastics, clearer films, more water resistance, and easier spraying, which makes it easier to work with floor adhesives. Plus, they can handle more fillers.

APEO Removal

When making dispersions for adhesives, we don't need to use surfactants with APEOs (alkylphenol ethoxylates). So, VINNAPAS dispersions meet tougher environmental standards (such as VINNAPAS EP 7000).

Unique Advantages of Aluminum Nitride Ceramics

Compared to conventional alumina (Al₂O₃) ceramics, aluminum nitride (AlN) ceramics offer the following distinctive advantages:

The most significant advantage of AlN is its extremely high thermal conductivity, with a theoretical value reaching 320 W/(m·K), which is 5–10 times that of alumina. This means that under the same operating conditions, AlN ceramics can withstand higher heat flux densities. As a packaging substrate or casing, AlN ceramics are particularly beneficial for heat dissipation in high-power chips or modules. When fabricated into AlN metal-ceramic heating elements (AlN Ceramic Heaters), they enable rapid heating. When made into electrostatic chucks (Electro-Static Chucks), they allow for quick preheating/heating of adsorbed wafers.

AlN has a low coefficient of thermal expansion (CTE) of only 4.3 ppm/K, which is close to that of silicon chips (3.5–4.0 ppm/K). This means there is a natural, high degree of thermal expansion matching between silicon chips and AlN ceramics, inherently improving packaging reliability.

Additionally, AlN ceramics exhibit mechanical properties, electrical performance, and corrosion resistance comparable to those of alumina ceramics.

AlN ceramics combine high thermal conductivity, low thermal expansion, high strength, and chemical corrosion resistance, making them ideal heat dissipation materials, especially for applications in large-scale integrated circuits and high-performance electronic devices.

Factors Affecting the Thermal Conductivity of AlN Ceramics

Since AlN ceramics are insulating solids, the contributions of electron and photon heat transfer are negligible. Their primary heat transfer mechanism is phonon (lattice vibration) conduction. The Al-N bonds in AlN ceramics have high bond energy and short bond lengths, resulting in high phonon propagation speeds, which explains their high thermal conductivity.

Although the theoretical thermal conductivity of AlN can reach 320 W/(m·K), currently only a few companies can produce AlN ceramics with thermal conductivities of up to 230 W/(m·K). Typically, the actual thermal conductivity of commercial products ranges from 150–180 W/(m·K). The factors affecting the thermal conductivity of AlN ceramics are as follows:

From a microscopic perspective, grain boundaries, interfaces, secondary phases, defects, and phonon scattering in the crystal structure all influence phonon transmission. From practical experience, the main factors affecting the thermal conductivity of AlN ceramics include lattice density, oxygen content, raw powder purity, and microstructure.

1、Density

Samples with low density contain numerous pores, which scatter phonons and reduce their mean free path, thereby lowering the thermal conductivity of AlN ceramics. Additionally, low-density samples may fail to meet the mechanical performance requirements for certain applications.

2、Oxygen Content

Due to the strong affinity between AlN and oxygen, the surface of AlN readily oxidizes when exposed to air or moisture, forming an alumina film. This introduces aluminum vacancies and oxygen defects, which can diffuse into the AlN lattice during sintering. Once these defects spread throughout the AlN crystal network, the mean free path of phonons is reduced, leading to a decline in thermal conductivity.

3、Lattice Defects

Research has found that the types of defects in AlN (aluminum nitride ceramic) lattices are related to oxygen atom concentration.

When the oxygen concentration is below 0.75%, oxygen atoms are uniformly dispersed in the AlN lattice, substituting nitrogen atoms and generating aluminum vacancies.

When the oxygen concentration is 0.75% or higher, the positions of aluminum atoms in the AlN lattice shift, eliminating aluminum vacancies and creating octahedral defects.

At higher oxygen concentrations, the lattice develops extended defects such as polytypes, inversion domains, and oxygen-containing stacking faults.

Measures to Improve the Thermal Conductivity of AlN Ceramics

1、Increase Density

Use fine-grained, highly sinterable micro/nano powders, incorporate sintering aids, or employ high-energy physical-assisted sintering methods to enhance the sintered density of the ceramics.

2、Reduce Oxygen Content and Internal Defects

Select high-purity, low-oxygen raw powders. Ensure that the storage of raw powders and the forming of semi-finished products avoid moisture exposure. Strictly control oxygen levels during atmosphere sintering.

When discussing polymer materials, we often hear comments like “this material has excellent rigidity” or “that one has outstanding toughness.” Materials with high rigidity usually exhibit greater hardness and resistance to compression and deformation. On the other hand, tough materials are more like flexible ribbons, capable of withstanding stretching and bending with remarkable resilience.

But have you ever wondered: what performance indicators truly define a material’s rigidity or flexibility? And what fundamental factors determine whether a polymer behaves as stiff or soft? In this article, we’ll explore these questions and uncover the science behind the mechanical characteristics of polymer materials.

Understanding Rigidity and Flexibility Through Performance Indicators

Among the many mechanical properties of polymer materials, different indicators are responsible for reflecting either rigidity or flexibility.

Indicators of Rigidity:
Flexural modulus and hardness are often seen as the key representatives of rigidity. The flexural modulus measures a material’s resistance to bending deformation—the higher the value, the “stiffer” the material, making it less prone to bending. Hardness, on the other hand, directly reflects a material’s ability to resist localized surface pressure. Materials with high hardness can better maintain their shape and resist compressive deformation from external forces.

Tensile strength and compressive strength also help indicate a material’s rigidity to some extent. Tensile strength is the maximum stress a material can endure before breaking under tension. A high tensile strength means the material can withstand greater pulling forces without breaking, showcasing strong rigidity. Similarly, compressive strength reflects a material’s ability to resist compression—higher values indicate stronger rigidity.

Indicators of Flexibility:
Elongation at break and impact strength are key indicators for evaluating a material’s flexibility.

Elongation at break refers to the ratio of the material's extended length to its original length when it breaks under tension. The higher the value, the more a material can stretch before breaking, indicating better ductility and flexibility.

Impact strength measures a material’s ability to absorb energy under sudden impact. Materials with high impact strength are less likely to fracture when subjected to external forces, demonstrating excellent toughness and flexibility.

Example: PP + 40% Long Glass Fiber

Understanding Rigidity and Flexibility Through Intrinsic Factors

2. Local Degrees of Freedom
The local structure and functional groups along polymer chains also affect material rigidity and flexibility. The size, polarity, and quantity of side groups play important roles. Larger side groups hinder the movement of polymer chains, reducing flexibility and increasing stiffness. For example, bio-based polymers with long alkyl side chains show increased rigidity as the side chain lengthens. Polar side groups generate strong intermolecular interactions that further restrict chain mobility and enhance stiffness. Bio-based cellulose derivatives containing polar groups such as hydroxyl and carboxyl can have their rigidity and flexibility tuned by adjusting the number and distribution of these groups.

3. Intermolecular Forces
The strength of intermolecular forces directly impacts polymer rigidity. Stronger interactions like hydrogen bonding and van der Waals forces increase the binding between polymer chains, making it harder for chains to slide or move relative to each other, thus raising the material’s stiffness. For example, chitosan exhibits abundant hydrogen bonding between molecules, resulting in high rigidity and strength, which is why it is widely used in biomedical applications like wound dressings. Conversely, weaker intermolecular forces facilitate chain mobility, yielding more flexible materials.

4. Molecular Chain Length
Molecular chain length acts as a double-edged sword for rigidity and flexibility. Generally, longer chains increase entanglement between molecules, restricting chain movement and increasing stiffness. However, longer chains also provide more conformational freedom, offering additional modes of movement that can impart some flexibility. For bio-based polyhydroxyalkanoates (PHA), increasing the degree of polymerization (chain length) enhances tensile strength and hardness while maintaining a degree of flexibility suitable for diverse applications.

5. Crosslinking
Crosslinking refers to chemical bonds connecting polymer chains into a three-dimensional network. In lightly crosslinked materials, the chains still retain some mobility between crosslink points, preserving flexibility while increasing stiffness and strength due to the network structure. For instance, lightly crosslinked sodium alginate hydrogels have good flexibility to conform to skin and sufficient strength for wound care. Highly crosslinked materials severely restrict chain motion, making the material hard, brittle, and significantly more rigid with greatly reduced flexibility.

6. External Factors
Temperature significantly influences polymer rigidity and flexibility. As temperature rises, increased molecular thermal motion enhances chain mobility, increasing flexibility and reducing stiffness. Lower temperatures have the opposite effect. Humidity also affects some hydrophilic bio-based polymers; for example, cellulose-based materials absorb moisture in high humidity environments, which weakens intermolecular forces, softens the material, and decreases stiffness.

Composite materials (such as carbon fiber reinforced composites and glass fiber reinforced composites) are widely used in the field of sports equipment due to their advantages of lightweight, high strength, and design flexibility.

Below are some typical application scenarios and specific examples:

Golf Clubs
Application Areas: Shaft, club head.

Resin Manhole Cover (Composite Manhole Cover)

The Application and Advantages of Resin Manhole Covers
Resin manhole covers are playing an increasingly important role in our daily lives. They stand out due to their self-cleaning properties and wide range of applications.

When used on roadways, resin manhole covers offer several benefits: they are electrically insulating, noiseless, have no recyclable value, and are naturally theft-resistant—making them an irreplaceable alternative to traditional cast iron covers.

Manufactured through a unique molding process, resin manhole covers bring a fresh aesthetic to urban environments. With a typical service life of 20 to 50 years, these high-temperature-formed composite covers offer a range of advantages: lightweight yet high strength, excellent fatigue resistance, safety in case of breakage, easy molding, low noise when driven over, strong chemical and acid/alkali resistance, and a clean, attractive appearance. Additionally, they help reduce pollutants in wastewater.

Currently, manufacturers use a variety of materials to produce composite manhole covers, but the main features are largely similar:

Excellent Anti-Theft Performance
Composite covers are generally made from unsaturated resin, fiberglass, and other materials through a specialized high-temperature one-step molding process. The finished products have no recyclable value, and even extracting the internal reinforcement (such as steel bars) is extremely difficult.

Long Service Life
By using high-performance resins, fiberglass, and special production formulas, these covers ensure deep resin penetration into the fibers, significantly enhancing the bonding strength. This prevents internal damage under cyclic loading, ensures long-term durability, and avoids common problems like poor adhesion seen in inferior products.

High/Low Temperature Resistance, Excellent Insulation, and Strong Corrosion Resistance
The product is corrosion-resistant, non-toxic, and free of metal additives. It can be used in demanding and harsh environments. Covers produced by Baisite have passed national authoritative testing, with outstanding performance in acid and alkali resistance, corrosion resistance, and anti-aging—meeting all relevant quality standards.

The surface can also be made to simulate various stone textures and colors to match surrounding pavement.

Strong Load-Bearing Capacity
The bottom structure of the cover features a special design. The continuous reinforced fibers used are integrated with fiberglass cloth, ensuring a solid structure and providing excellent load-bearing performance.

Eco-Friendly, Anti-Slip, and Low Noise
When driven over by vehicles, the cover remains non-slip, produces no harsh noise, and causes no pollution—making it a safer and more environmentally friendly solution.

Butvar brand resins generally are soluble in alcohols, glycol ethers, and certain mixtures of polar and nonpolar solvents. In general, Butvar B-98 (PVB Resin B-05SY) resin will show the same general compatibility characteristics as Butvar B-90 (PVB Resin B-02HX) and, therefore, should prove advantageous where physical and chemical properties of B-90 are desired but lower solution viscosities are necessary. The same is true for Butvar B-79 in relation to Butvar B-76.

The lower hydroxyl content of Butvar B-76 and Butvar B-79 permits solubility in a wider variety of organic solvents as compared to the other grades of Butvar. One notable exception, however, is the insolubility of Butvar B-76 and Butvar B-79 in methanol. All other types of Butvar contain sufficient hydroxyl groups to allow for solubility in alcohol and in hydroxyl-containing solvents. The presence of both butyral and hydroxyl groups permits solution in mixtures of alcohol and aromatics. Viscosities of Butvar resin solutions containing mixed solvents depend on the ratio of alcohol to aromatic. Viscosity curves for Butvar B-76, Butvar B-90, and Butvar B-98 in Graph 2 show minimum points in the general vicinity of 50% alcohol: 50% aromatic.

A common solvent for all of the Butvar resins is a combination of 60 parts toluene and 40 parts ethanol (95%) by weight. For compositions of Butvar, methyl alcohol will tend to give the lowest viscosity and, therefore, will permit the use of higher solids when used as a component of a solvent blend. When much more than 10% to 15% alcohol is used in a formulation for spray application, blushing may result. They are useful as starting points in the development of solvent blends for the other types.

The scientific name of PVB resin is polyvinyl butyral resin. It was successfully industrialized in the United States in the 1930s and has a history of more than 70 years. my country has been trying to industrialize it since the 1960s, but due to the sensitivity of raw materials and process parameters, the product quality fluctuates greatly. The few finished products can only meet military purposes. It was not until the 1990s that a small amount of PVB (B-06HX &PVB B-20HX) products entered the civilian market.

Due to the different processes of PVB manufacturers, the requirements for PVB quality indicators are also different. Not only are there certain restrictions on the viscosity range, but there are also clear requirements for many indicators such as acetalization degree, tensile strength, and film-forming properties. Therefore, it is very easy to make PVB resin. However, it is quite difficult to make products that satisfy users. In order to produce PVB resins that meet user needs and improve the qualified rate of products, the following countermeasures should be taken:

Carefully select raw materials PVA

PVA has a variety of models (such as PVA 088-50 & PVA 2488, Mowiol 47-88), not only with different degrees of polymerization, but also with different degrees of alcoholysis. To figure out how much acetalization you need, pick a PVA that meets the viscosity requirements. Try to keep the process conditions the same so that the product quality stays good without putting in extra effort.

Process control programming

At present, the production of China PVB resin adopts two-step precipitation method, kettle operation, and intermittent production. The production control is mainly manual control, which is quite arbitrary, especially the viscosity of PVB. The viscosity changes greatly with a slight change in the process.It's a good idea to use a DCS control system for making PVB resin. Stick to a programmed operation and keep the process steps pretty much the same for each customer.

Strict finished product management

It is best to adopt order-based production, and deliver it to customers in time after production is completed. Products that have not been delivered to customers must be placed separately and must not be mixed. For products that have been parked in the warehouse for more than one month, re-sampling and analysis are required before leaving the factory to prevent degradation of PVB resin powder.

Disposal of unqualified products

Some products may not meet the requirements of a certain user for individual indicators, but there is no problem with the quality of the batch of products itself. The usual practice is to find users with the same or similar quality as the batch of products and make appropriate treatments based on the degree of compliance. If the same products can be sent directly to the user, if the same products are not met, measures such as return package and add can be taken. Products with quality problems can only be sold as waste or destroyed.

The different kinds of Butvar resins have their properties laid out in Tables 1 to 5. These resins come in various molecular weights and viscosities. Butvar 76 and Butvar 79 resins have less hydroxyl content compared to other Butvar options, which gives them better solubility.

Generally, when you swap butyral groups for acetate groups, you get a polymer that repels water better and can handle heat more without deforming. This change also boosts the polymer's strength and how well it sticks to different surfaces. The strong sticking power of polyvinyl butyral resins comes from their terpolymer structure. Since each molecule has a choice of three different functional groups on its surface, the likelihood of adhesion to a wide range of substrates is significantly increased.

Although polyvinyl butyral resins (PVB) are generally thermoplastic and soluble in a number of solvents, they can be crosslinked by heat and small amounts of mineral acid.Crosslinking often happens through transacetalization, but it can also be due to more complicated processes, like reactions between acetate or hydroxyl groups on nearby chains.

In practice, crosslinking of polyvinyl butyrals is achieved by reaction with various thermosetting resins such as phenolic, epoxy, urea, dicyanate, and melamine resins. The availability of functional hydroxyl groups in Butvar resins for this type of condensation is an important factor in many applications. Including even a small amount of Butvar resin in thermosetting compositions will significantly improve the strength, flexibility, and adhesion of the cured coating.

Polyvinyl butyral films are known for their great resistance to various substances like aliphatic hydrocarbons and different kinds of oils, except for castor and gypsum oils. They tolerate strong bases, but are sensitive to strong acids. However, when used as components of cured coatings, their resistance to acids, solvents and other chemicals is greatly increased. Butyral withstands temperatures up to 200°F for long periods with little color change.

We used partially alcoholysis PVA-217SB (PVA080-22 & PVA1780) and high-efficiency environmentally friendly pulp together, and added a certain proportion of starch. We conducted experiments on several polyester-cotton varieties, which not only significantly improved the pulp shaft quality, but also greatly reduced the pulp cost.

Pulp performance:

The chemical structure of PVA varies depending on the degree of alcoholysis. PVA with an alcoholysis degree of 99.6% is fully alcoholysis, like the PVA-1799 (PVA 100-27) we usually work with. On the other hand, PVA with an alcoholysis degree of 88% is partially alcoholysis, such as PVA-1788 (PVA 088-20) and PVA-217SB. The fully alcoholysis PVA mainly has hydroxyl groups in its structure, whereas the partially alcoholysis version contains some ester groups along with hydroxyl groups. This difference makes their performance quite distinct. For example, when mixing partially hydrolyzed PVA with completely hydrolyzed PVA and starch, the starch ratios needed aren't too different between the two. Generally, it should not exceed 70%, that is, the starch to PVA mixing ratio is generally about 7:3, in order to obtain a slurry with good miscibility. Runli's eco-friendly slurry is a milky white liquid that has over 98% effective ingredients. It has a viscosity of 2 to 8 mPa·s at 20℃ and a pH level between 7.5 and 8.5. This slurry flows well, has good elasticity, strong adhesion, mixes easily with other slurries and additives, and it's simple to remove after use.

Summary:

(1) From the trial, tracking, and test analysis of Runli slurry and partially hydrolyzed PVA, we found that the slurry flow rate is stable and it is not easy to form sizing skin at low temperature. The thousandth reel is smooth, the sizing yarn feels smooth, and there is less regenerated hairiness.

(2) The new sizing yarn indicators are way better than the old formula. We’ve seen a big drop in loom breakage and a solid increase in the good axis rate and loom efficiency.

(3) The use of Runli sizing agent and partially alcoholysis PVA (PVA-217SB) sizing agent has greatly reduced the sizing cost.
