Usage: Zinc oxide used in rubber or cables; can make rubber be better in corrosion resistance, tear resistance and elasticity. And also used as vulcanization activator of natural rubber, coloring agent and filler of white rubber, vulcanizing agent of chloroprene rubber. Those of fine particles (particle size around 0.1um) can be used as light stabilizing agent of plastics including polyolefin or chloroethylene, etc.
