Silica for High-Grade Rubber
FINE-SIL365 and FINE-SIL518 are high-transparency and high-reinforcement silica products for silicone rubber. They offer better reinforcement than ordinary precipitated silica in the rubber industry. Especially in the silicone rubber industry, they not only endow products with excellent tensile strength and wear resistance, but also ensure good transparency, excellent color and appearance, no whitening under tension, and no deformation.
