RUBBER GRADE PRECIPITATED SILICA


SUPERSIL - 140 gives high dispensability, makes it better reinforcing silica and suitable for filling a natural, synthetic and latex rubber, transparent shoe soles, tyres, tubes, rubber lining, vulcanization of rubber etc. to provide toughness and high resistance to abrasion.



RUBBER GRADE PRECIPITATED SILICA

RUBBER GRADE PRECIPITATED SILICA

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.
It is a high-quality, reinforcing particulate filler that is used in conjunction with carbon black in rubber components of tyres and mechanical goods to improve performance
Precipitated silica are mainly used as a reinforcement agent in rubber and tyre formulations. They are additionally utilized as carriers. It imparts good finish, strength and balances at the required physico-chemical properties of the products.
