Indirect method of zinc oxide (1314-13-2)
Negotiable
Category: Chemicals/Catalysts & Additives/Accelerators
Company: Shandong RICH Chemical Co., Ltd.
Product Description: 1、Characteristics:
1. Zinc oxide has smaller particle size, stronger activity, uniform particle size, and stronger dispersion than ordinary zinc oxide. It has a good promoting effect on vulcanization, increases the cross-linking density of vulcanized rubber, and makes vulcanization more thorough.
2. It can effectively improve the viscosity of the rubber material and enhance the adhesion between rubber, steel wire, curtain and other skeleton materials.
3. Good dynamic mechanical properties, small deformation, low heat generation, and good wear resistance of rubber products make them have good aging resistance.
2、Purpose:
Zinc oxide is mainly used in the production of rubber products such as radial tires, diagonal tires, conveyor belts, rubber hoses, tapes, rubber shoes, latex gloves, etc. Its product performance fully meets the requirements of the national, chemical department, and American ASTM standards.
3、Product execution standard GB/T3185-92
