Plastic Filler High Whiteness Anhydrous Transparent Powder
Anhydrous transparent powder is an advanced powder material with properties such as good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, stable chemical performance, and high hardness. It is widely used in coatings, paint topcoats, adhesives, transparent masterbatches, silicone rubber, transparent glass adhesives, and other industries.
1. Anhydrous transparent powder appears as a white powder and can withstand temperatures from -50°C to 1600°C. Bulk density: 0.8 g/cm³, true density: 2.0 g/cm³.
2. Fineness of anhydrous transparent powder: average fineness 1–12 μm, average particle size 1–3 μm, specific surface area: 2–2.8 m²/g. Common specifications include average particle sizes of 1250 mesh, 2500 mesh, 6000 mesh, and 8000 mesh.
3. Particle morphology: During processing, amorphous spherical particles with relatively smooth surfaces are formed due to surface tension during phase transformation. It is a material with a large specific surface area and high activity. In specific environments, the tiny spherical particles can act as lubricants.
4. Excellent insulation: Due to its high purity, low impurity content, stable performance, and excellent electrical insulation properties, it provides the cured product with good insulation and arc resistance.
5. Reduces the peak exothermic temperature of plastic curing reactions, lowers the linear expansion coefficient and shrinkage rate of the cured product, thereby eliminating internal stress and preventing cracking.
6. Corrosion resistance: Anhydrous transparent powder does not easily react with other substances and is chemically inert to most acids and alkalis. Its particles uniformly cover the surface of objects, providing strong corrosion resistance.
7. Reasonable particle distribution enhances the tensile and compressive strength of molded plastics, improves wear resistance, increases thermal conductivity, and enhances flame retardancy.
8. As a filler added to plastics, anhydrous transparent powder not only improves various properties of plastics but also reduces product costs.
Functions
1. Enhances material hardness, significantly improves scratch and wear resistance, suitable for high-end topcoats;
2. Excellent optical properties, absorbs some blue light, good recoatability, slight matting without affecting coating transparency;
3. Uniform particle size distribution, good anti-settling properties, low oil absorption, reduces resin usage and lowers costs;
4. Extremely low iron content, high purity, does not affect the color of the paint film.
