Nano silica for rubber reinforcement ug-sp175

  █ product characteristics: it is a very good rubber reinforcing agent
It can improve the tensile strength and wear resistance of vulcanized rubber, reduce the amount of rubber, reduce the cost, have strong affinity, and make it have greater dispersion ability in raw rubber
The physical property formed by the particles of white carbon black and rubber molecules is better than that of carbon black in enhancing the mechanical strength and tear strength of vulcanized rubber
