Product Content

RUBBER GRADE ZINC OXIDE

Use:
Rubber grade zinc oxide is used in series of products such as steel radial tyre, bias tyre, conveyer belt, rubber tube and tape, rubber shoes, emulsion glove productions etc. Its properties of product can meet country, the Ministry of Chemical Industry and American ASTM standard requirements.

Characteristic and function ：


1.High activity, even granularity, it’s possessed of high dispersing ability, has the good promotion curing function, improve the cross-link china density of rubber, enable to make the rubber vulcanization more completely.

2. It can improve the viscidity of rubber compound,and the adhesive force of materials such as the rubber, steel wire and code fabric, etc.

3. It can make good dynamic performance, make the rubber products with little deformation, low heat generation, high anti-abrasion. Enable to have good anti-oxide property.
