Precipitated Silica
Precipitated Silica is an active filler and reinforcing agent in rubber tyres and rubber products, which can improve the mechanical properties, abrasion resistance, and thermal properties It can also improve the tensile strength, tear strength, abrasion resistance and flexibility of rubber products and tires.
ELD 115
ELD-115 with low specific BET surface area combines high dispersion and reinforcement with improved processing behavior. This type of silica is for all kinds of green tyres, especially suited to high filler loadings for optimization of wet and winter(snow) road holdings.
