Zinc Oxide 90%/95%/99%/99.5%/99.7%/99.9%Min
Product synopsis:
Industrial Zinc Oxide
Zinc content: 99.0%, 99.5%, 99.7%
Character:
White powder, density 5.606, melting point 1975 cent degree, double gender oxide, can't dissolve in water or grain alcohol, dissolve in acid or alkali liquor. Yellow color under high temperature, back to white after cooling
Comparing with others, Industrial Zinc Oxide has the following advantages:
1. Small diameter, granularity uniformity, high disperse ability, chemical reaction speed quickly, completely and simultaneously.
2. High content, high pure degree product with this material, strong stability, little impurity, reduce greatly effects of main products from other resultant.
3. Single granule density small, specific gravity small, can't deposit easily during reaction processing.
4. Pure white color, no effect for products after reaction.
Use: Rubber, paints, medicine, ink, cable, electron, coinage, ceramic, match, chemical, cosmetic and other industrial materials
