(1) Reinforcement: The tear strength of the compound reinforced with silica can be significantly improved. Therefore, about 10-25 parts of silica are usually added to the tread compound of many large-sized tires, which can significantly improve the tire tread. excellent resistance to cutting chipping.

It should be noted that when using white carbon black to improve the tear strength of rubber products, with the increase of the amount of white carbon black, the wear resistance of the rubber compound will decrease, and the amount of white carbon black should be reasonably controlled.

(2) Adhesion: The surface of silica has active silanols, which is an important part of the adhesion system of m-methyl white.

In actual production, the meta-naphthalene adhesive system can significantly improve the adhesive strength between rubber and skeleton materials (including cotton, nylon, polyester, steel wire, etc.).

ZC140 Powder Precipitated Silica for Rubber

ZC140P Silicon Dioxide possesses a high reinforcing potential and imparts rubber compounds as the lower specific surface. It can improve high Shore hardness, tensile strength, tear resistance and abrasion resistance, less deformation under compression, and extended products life.
