Rubber Grade
- Precipitated silica is mainly used as rubber strengthening agent and additives.
- It can be used to manufacture white, transparent rubber products.
- Precipitated Silica is used to improve rubber tear strength, flex fatigue resistance, abrasion resistance, heat build-up, hardness, modulus, resilience and adhesion.
- Due to the high surface area and purity of our product, vulcanization can be made with excellent transparency, enhanced strength properties, tear / shear hardness and abrasion resistance.
