zinc oxide 99.7%Characteristics and functions:
1.It has strong activity, uniform particle size and strong dispersion. It plays a good rule in the promotion of vulcanization. It can increase the crosslink density of vulcanized rubber and vulcanizes more completely.
2. It can better improve the rubber viscosity and improve the adhesion between rubber and skeleton materials such as steel wires and curtain fabric.
3. Rubber has good Dynamic performance, small deformation, less heat production, nice wearability and good resistance to aging
