Zinc oxide for rubber
Product Introduction
I. Features:
1. Xingyuan brand rubber-grade zinc oxide has smaller particle size, stronger activity, uniform particle size distribution, and strong dispersibility than ordinary zinc oxide. It has a good promoting vulcanization effect, improves the crosslinking density of vulcanized rubber, and makes vulcanization more thorough.
2. It can better improve the tackiness of the rubber compound and enhance the adhesion between rubber and reinforcing materials such as steel wire and fabric.
3. It has good dynamic mechanical properties, small deformation of rubber products, less heat generation, good wear resistance, and good aging resistance.
II. Applications:
Xingyuan brand rubber-grade zinc oxide is mainly used in the production of radial tires, bias tires, conveyor belts, rubber hoses, rubber tapes, rubber shoes, latex gloves and other rubber products. Its product performance fully meets the requirements of national standards, Ministry of Chemical Industry standards and American ASTM standards.
III. Product Execution Standard GB/T3185-92
