Characteristics and Effects:
1. It has strong activity and dispersity, uniform granularity and good effect of accelerated sulfur vulcanization, improves crosslinking density of vulcanizate and makes vulcanization more thorough.
2. It can improve rubber viscosity and adhesion of framework materials, including rubber, steel wire and cord fabric.
3. It has good dynamic properties, so that rubber products have little deformation, less heat and good wear resistance, ensuring good ageing resistance of these products.

Application:
Rubber grade zinc oxide is used for production of rubber products, such as radial tires, diagonal tires, conveyor belts, rubber pipes, adhesive tapes, rubber shoes and latex gloves. Its product properties fully meet standards of the country, Chemical Industry Ministry and American ASTM.

Packaging and Transport:
1. Inner plastic and outer braiding double-layer packaging.
2. Standard bag weight: 25kg.
3. Package according to customer demands.
4. Guard against damp during transport and storage.
