With strong activity, uniform particle size and good dispersion, it can promote vulcanization, improve the crosslinking density of vulcanizate and make vulcanization more thorough.It can better improve the viscosity of materials and improve the adhesion of rubber, steel wire, cord fabric and other framework materials.Good dynamic mechanical properties, small deformation, less heat generation and good wear resistance of rubber products, so that they have good aging resistance.
