Philosophy & Chemical Properties: this product has a medium-performance reinforcement. Compared with N762 and N772, the benzene light transmittance slightly higher (95%), the structure is also slightly higher. Its main characteristic is the low solvent extract, do not pollute the rubber.

Application: It is used in buffer layer and for the tire carcass ply rubber hose, pressure products, and all kinds of industrial rubber products as well as wires, cables, etc.

Function: the process performance of this rubber mass which is used carbon black N774 is better, high filler content, high elongation of the vulcanized rubber, low-heat, high flexibility and good aging resistance. This product can also replace the thermal cracking method carbon black.
