Precipitated silica, an amorphous form of silicon dioxide, is a vital ingredient in a wide array of applications worldwide. Added during manufacturing, these materials provide reinforcement and performance benefits across various industries.

In particular, precipitated silicas have become a key filler used in the rubber industry, valued for their ability to enhance mechanical properties such as hardness, abrasion resistance, and tensile and tear strength. As a result, they are commonly used as white reinforcing fillers in products like tires, shoe soles, hoses, belt conveyors and thermoplastic elastomer compounds.
