What is rubber-grade zinc oxide?

2022-05-18

Rubber-grade zinc oxide is a white hexagonal crystalline powder, odorless, non-toxic, fine in texture, with special small size effect and surface activation effect. It is an active additive. Compared with indirect zinc oxide and direct zinc oxide, this product has a larger specific surface area, therefore, it has higher activity and good dispersibility in application. Rubber and plastic-specific active zinc oxide has low content of heavy metal impurities...

　　Zinc oxide, also known as zinc suboxide and zinc oxide powder, is a pigment-type environmentally friendly inorganic polymer material (coating) mainly based on zinc metal. It is widely used both domestically and internationally; it features excellent wear resistance and moderate hardness, and its products have bright and non-fading colors. Our company can provide various zinc oxide products according to customer requirements.

　　 Rubber-grade zinc oxide It is a white hexagonal crystalline or powder, odorless, non-toxic, fine in texture, with special small size effect and surface activation effect. It is an active additive. Compared with indirect zinc oxide and direct zinc oxide, this product has a larger specific surface area, therefore, it has higher activity and good dispersibility in application. The rubber and plastic-specific active zinc oxide has low heavy metal and other impurity content, strong activity, easy dispersion, fine particle size, and large surface area. It is a substitute for traditional zinc oxide and has better use characteristics than ordinary zinc oxide.


Rubber-grade zinc oxide


　　Rubber-grade zinc oxide is mainly used as a reinforcing agent for rubber, making the rubber have good tear resistance, corrosion resistance, elasticity, and elongation. The promoter used is a multifunctional rubber compounding agent in the rubber vulcanization process, mainly used as a vulcanization reinforcing agent and activator for synthetic rubber, natural rubber, and latex. When used as a vulcanization activator, it has a large contact area with hydrogen sulfide, is evenly distributed in the rubber, and has many interfacial reaction opportunities. In addition, the conversion rate of this active zinc oxide product to zinc sulfide is very high under the catalytic action of the active substance.

　　As a vulcanizing oxidant, its function is to reduce the amount of promoter, improve the activity of the promoter, and shorten the vulcanization cycle. It can improve the thermal conductivity of vulcanized rubber, accelerate the vulcanization speed, and make the vulcanization better. In the rubber industry, especially in the production of transparent rubber products, active zinc oxide is an excellent vulcanization activator.
