A zinc oxide, zinc oxide, also known as white oxygen, molecular formula: ZnO, molecular weight:? 81.38 Second, the role of zinc oxide and zinc EVA foam rubber and tire industries oxide is indispensable additives, but also as natural rubber, synthetic rubber, and EVA vulcanization active agents and reinforcing agents have been coloring agent. Zinc oxide can be fully used in rubber vulcanization accelerators, and improve the properties of rubber. Three characteristics? 1 activity, precision uniform dispersion of good, has a good role in promoting vulcanization,? Raise the crosslink density of vulcanized rubber, sulfide more thoroughly. 2, can better improve the material viscosity, improve rubber and wire and cord and other reinforcing material adhesion. 3, dynamic mechanical properties, small deformation of rubber products, less heat, abrasion resistance, it has good resistance to aging. ?
