Reinforcement and reinforcing mechanism of styrene

Precipitated silica has been established as the most important non-black filler system for rubber industry. For instance, styrene–butadiene rubber (SBR)/ silica nanocomposites have been widely used in green tire, where silica is introduced into SBR for enhancing the mechanical properties and reducing the rolling resistance of the composites [8].

precipitated silica

Precipitated silica

Precipitated silica is an amorphous form of silica (silicon dioxide, SiO2); it is a white, powdery material. Precipitated silica is produced by precipitation from a solution containing silicate salts. The three main classes of amorphous silica are pyrogenic silica, precipitated silica and silica gel.
