Previous PageChemical Grade Zinc Oxide
1. Features
(1) The zinc oxide has smaller particle size than the common zinc
oxide, strong activity, uniform particle size, strong
dispersibility and good effect of promoting vulcanization, improves
the crosslinking density of vulcanized rubber, and makes
vulcanization more thorough.
(2) The zinc oxide can well improve the viscosity of rubber
materials and improve the adhesion of rubber, steel wires and
framework materials such as cord fabrics.
(3) The zinc oxide has good dynamic mechanical properties, and
rubber products have small deformation and heat production amount
and good wear resistance and ageing resistance.
2. Application:
The zinc oxide is mainly used for producing rubber products such as
radial tires, diagonal tires, conveyor belts, rubber tubes, rubber
belts, rubber shoes and latex gloves. Product performance
completely meets the requirement of Ministry of Chemical Industry
and ASTM standard.
3. Product Executing Standard GB/T3185-92
