Especially in the silicone rubber industry, it not only makes the products have good tensile strength and wear resistance
Fine-sil365 and fine-sil518 silica products for high transparency and high reinforcement silicone rubber have more reinforcement than ordinary precipitated silica in the rubber industry. Especially in the silicone rubber industry, they not only make the products have good tensile strength and wear resistance, but also make the products have good transparency, excellent color and appearance, no return to white and no deformation.
