Application of active zinc oxide for rubber:

1. Active zinc oxide for rubber improves the thermal conductivity, wear resistance, tear resistance, tensile strength and other indicators of products in the tire industry, such as in black and dark rubber tires and radial tires.

2. Active zinc oxide for rubber promotes the vulcanization, activation and reinforcement of rubber in synthetic rubber, anti-aging effects, can strengthen the vulcanization process, and improve the tear resistance and wear resistance of rubber products.

3. Active zinc oxide for rubber is used as a vulcanization activator in natural rubber to promote rubber vulcanization, activation and reinforcement, and anti-aging effects, can strengthen the vulcanization process, and improve the tear resistance and wear resistance of rubber products.

4. Active zinc oxide for rubber is used as an activator in latex to promote rubber vulcanization, activation and reinforcement, anti-aging effects, can strengthen the vulcanization process, and improve the tear resistance and wear resistance of rubber products.

5. Used as colorant and filler in white latex.

6. Active zinc oxide for rubber is used in labor protection products such as rubber shoes, rain boots, rubber gloves, etc., to improve wear resistance and anti-aging, and prolong service life.

7. Active zinc oxide for rubber is an essential inorganic active agent for the manufacture of transparent rubber and food rubber products.
