Product Description

 

Product Description

a. In high-temperature and room-temperature silicone rubber products, our advanced ultrafine silica enhances transparency, wear resistance, and tear resistance, while also improving dielectric properties and providing superior high-temperature resilience.
b. In paint, coatings, and ink products, it contributes to thickening, thixotropy, matting, dispersion, anti-precipitation, anti-caking, and sag resistance, while optimizing stability, water content regulation, free-flow properties, and electrostatic applications.
c. In adhesive products, it reinforces, thickens, enhances thixotropy, reduces precipitation and caking, aids in processing, and improves stability and adhesion.
d. In resin, glass fiber-reinforced plastic products, and composite products, it prevents sagging, enhances aging and impact resistance, improves strength, and ensures a smooth surface finish.
e. In plastic film products, it offers aging and impact resistance, prevents foam cracking, and enhances strength and transparency.
