Rubber grade zinc oxide99.7% powderadded to rubber will react with accelerators to form zinc salt complexes. The 2n2+ particles containing empty orbitals have a strong polarization ability and are easy to promote the cracking of sulfur ring molecules to promote rubber vulcanization.

Why should rubber grade zinc oxide99.7% powder  be used in conjunction with stearic acid in rubber? Because in the rubber processing process,rubber gradezinc oxide 99.7% powderand rubber molecules are positively charged and repel each other with the same sex. It is difficult to disperse in rubber. When added together with stearic acid, during the mixing process, zinc stearate is easily dispersed. Up.

MST has been focusing on the production of zinc oxide for more than 30 years. Researchers have been studying to improve the quality of zinc oxide, such as reducing the content of lead, copper, manganese and other metals in zinc oxide.

MST continuously explores new uses of zinc oxide, and develops zinc oxide suitable for different products, such as rubber grade zinc oxide 99.7%, ceramic grade zinc oxide, glass grade zinc oxide, feed grade zinc oxide, etc.

Now using zinc oxide's strong ability to absorb waves, zinc oxide can be used on invisible materials.
