Product Description

 

Product Description.
--------------------------------
a. In high-temperature and room-temperature silicone rubber products, our Ultrafine Silica enhances transparency, wear resistance, and tear resistance. It also boosts dielectric properties, making it an indispensable component for high-performance applications.
b. In paints, coatings, and inks, our Ultrafine Silica excels in thickening, providing thixotropy, and achieving optimal dispersion. It prevents precipitation and caking, while enhancing stability and regulating water content for impeccable finishes.
c. For adhesives, our Ultrafine Silica is crucial for reinforcement, thickening, and thixotropy. It prevents precipitation and caking, improves processing, and significantly boosts stability and adhesion.
d. In resin and glass fiber reinforced plastic products, our Ultrafine Silica offers anti-hanging properties, aging resistance, and impact resistance. It improves strength and provides a smooth surface finish for superior performance.
e. For plastic film products, our Ultrafine Silica enhances aging resistance, impact resistance, and prevents foam cracking. It significantly boosts strength and transparency, ensuring top-tier quality.
