Milestone Industrial Co., Ltd. produces Zinc Oxide powder 99.7, a commonly used chemical additive, which is widely used in plastics, silicate products, synthetic rubber, lubricants, paints, ointments, adhesives, and food. The produced Zinc Oxide powder 99.7 has strong activity, uniform particle size, good dispersibility, and has a good effect of accelerating vulcanization, increasing the crosslinking density of the vulcanized rubber, and making the vulcanization more thorough.

Zinc Oxide powder 99.7 can enhance and promote the accelerator. The mechanism and method of Zinc Oxide powder 99.7 are as follows:

1) During the vulcanization process, Zinc Oxide powder 99.7 can react with accelerators, sulfur, stearic acid, rubber macromolecular chains, and corresponding intermediate products. Zinc oxide is used as a vulcanization activator, which is mainly used for chemical interaction during vulcanization. The formation speed of the link, the type and number of crosslinks have an important influence, thereby increasing the degree of crosslinking of the vulcanizate.

2) The reaction of Zinc Oxide powder 99.7 as an active agent with organic accelerators, stearic acid, sulfur, etc. occurs on the surface of zinc oxide particles during the vulcanization process. Because zinc oxide has a large affinity for electrons and a strong ability to adsorb accelerators, under the action of stearic acid, it generates soluble accelerator zinc salts, thereby increasing its solubility, and forming a compound with amines or fatty acids The zinc complex makes the accelerator more active. Sulfur is added to the complex to form a strong vulcanizing agent by inducing activation. During this process, the surface of the zinc oxide particles continuously reacts, the particle size is continuously reduced, and the zinc oxide is consumed until the rubber is fully vulcanized. With the change of the particle size of Zinc Oxide powder 997, its specific surface area and structure determine the activation of vulcanization.

MST has 46 professional production processes and production lines, with an annual output of 200,000 tons of high-grade zinc oxide; it has independent import and export rights, and its Zinc Oxide powder 99.7 is exported to Europe, the United States, Asia and other countries.
