Manufacture of 99.5% Zinc Oxide
Grade:
1.Rubber Grade of Zinc Oxide
Rubber grade zinc oxide is used in series of products such as steel radial tyre,bias tyre,conveyor belt rubber tube and tape,rubber shoes,emulsion glove productions etc.
2. Advanced ceramic Zinc Oxide
Advanced ceramics special zinc oxide is an important chemical flux of ceramic materials,and especially used in ceramic wall floor tiles in buildings with low-temperature enamel glazxe material.Zinc oxide is widely used in ceramic tile glazes and thick translucent glazing and thick translucent glazing and transparent process tableware dish cooked thick glaze or enamel.
3. Chemical Grade Zinc Oxide
Widely used in zinc stearate,zinc bromide,zinc borate,phosphate and other liquid products,and also can used to deeply electroplating solution.
4. Coating and paint grade Zinc Oxide
Used in the production of top-grade paint and coating intermediates.
