Silica for General Rubber
FINE Silica is an ultra-fine precipitated silica (commonly known as silica) produced through a special processing technology. It features excellent reinforcement and dispersion properties. Years of production practice have proven that it can completely or partially replace expensive fumed silica, greatly reducing customers' production costs.
FINE-SIL325 is suitable for reinforcement in tires, rubber shoes and other products, improving the flex resistance, anti-cracking performance and physical properties of the products. It can achieve high wear resistance, high strength and transparency, and prolong the service life of the products.
