Coating Performance Optimization in Titanium dioxide powder
- Sub-Micron Particle Size for High Coverage: Titanium dioxide powder from Shijiazhuang Yaguan New Material Technology Co., Ltd. uses a particle size distribution of 0.2-0.4 μm (optimal for light scattering) to maximize covering power—achieving a hiding power of 10-12 g/m² (per ISO 6504), 20% higher than powders with larger particles (0.5-0.8 μm). This makes it ideal for architectural coatings, and our clients report 30% less pigment usage to achieve full coverage, reducing coating costs by 15%.
- Narrow Size Distribution for Uniform Color: Titanium dioxide powder features a narrow particle size distribution (span <1.2), ensuring uniform dispersion in coating formulations. This eliminates color variations (e.g., streaks or spots) and improves gloss retention (90% gloss after 1000 hours of weathering, per ASTM D523), critical for high-end automotive coatings—our tests confirm the powder maintains consistent color across 100+ batches, meeting automotive OEM standards.
- Surface-Modified Particles for Weather Resistance: Titanium dioxide powder (0.3-0.5 μm) undergoes alumina-silica surface modification, enhancing its resistance to UV-induced degradation. Coatings using this powder retain 95% of their original color after 2000 hours of UV exposure (per ISO 11341), outperforming unmodified titanium dioxide powder by 40%—a key advantage for outdoor coatings like exterior wall paints.
Plastic & Paper Application Tuning in Tio2 powder
- Medium Particle Size for Plastic Compounding: Tio2 powder (0.4-0.6 μm) from Shijiazhuang Yaguan New Material Technology Co., Ltd. is optimized for plastic compounding, with a particle size that balances dispersion and mechanical properties. The powder disperses evenly in polypropylene and polyethylene (no agglomeration >5 μm), and our clients report plastic products have 25% higher impact strength compared to those using finer tio2 powder (0.2-0.3 μm), which can cause brittleness.
- Controlled Agglomeration for Paper Coating: Tio2 powder for paper coating has a controlled agglomerate size (5-10 μm) that improves paper opacity without compromising surface smoothness. The agglomerates fill paper pores while maintaining a uniform coating layer (thickness ±2 μm), and our tests show paper using this tio2 powder has an opacity of 92% (per TAPPI T425), meeting high-quality printing paper standards—used by 10+ global paper manufacturers.
- Heat Stability for High-Temp Plastics: Tio2 powderretains its particle size and color stability at temperatures up to 280°C (per ISO 787-23), making it suitable for high-temperature plastics like ABS and PC. The powder does not degrade or discolor during injection molding, and our clients in electronics report plastic housings using this tio2 powder maintain their white color (L* value >95) after 500 hours of heat aging—critical for consumer electronics aesthetics.
Cosmetic & Specialty Use in Tio2 white
- Nano-Scale Particle Size for Transparency: Tio2 white (10-50 nm) from Shijiazhuang Yaguan New Material Technology Co., Ltd. is engineered for transparent cosmetic formulations (e.g., BB creams, sunscreens). The nano-particles provide UV protection (SPF 30 when used at 5% w/w) without a white cast, and our in-vitro tests confirm they block 98% of UVA/UVB rays—meeting EU CosIng regulations for mineral sunscreens.
- Low Oil Absorption for Creamy Textures: Tio2 white has an oil absorption value of 18-22 g/100g (per ISO 787-19), lower than standard titanium dioxide powder (25-30 g/100g). This ensures it blends smoothly into creamy cosmetics (e.g., foundations) without making textures greasy, and our cosmetic clients report 90% consumer satisfaction with the product’s application feel.
- Heavy Metal-Free for Safety: Tio2 white from the company has heavy metal content (Pb, Cd, Hg) <0.1 ppm (per ICP-MS tests), complying with global cosmetic safety standards (e.g., FDA 21 CFR 73). The powder is also non-comedogenic, making it suitable for sensitive skin products—adopted by 8+ natural cosmetic brands for its safety and performance.
