Zinc Oxide (ZnO, CAS: 1314-13-2) is an inorganic oxide that appears as a fine white powder. We supply a range of grades, including indirect-process ZnO, direct-process ZnO, active zinc oxide, and nano zinc oxide. Featuring high purity, low heavy metal content, and consistent batch-to-batch quality, our products are widely used in rubber vulcanization activation, coating pigments, ceramic glazes, feed additives, and cosmetic sun care formulations. Customized particle size and heavy metal specification control are available, and we also offer sample testing and OEM packaging services.

Rubber industry: Serves as a vulcanization activator, enhancing tensile strength, wear resistance, and anti-aging performance. Commonly used in tires, hoses, and sealing strips.
Coatings & paints: Acts as a white pigment, providing anti-rust and UV-shielding effects.
Ceramics & glass: Used as a glaze flux to improve surface gloss.
Feed industry: Added to feed formulations as a zinc nutritional supplement.
Cosmetics & Personal Care: Functions as a physical UV filter and mild astringent in skincare preparations.
Plastics industry: Used as a light stabilizer and antibacterial modifier.
Others: Used as a desulfurizing agent and electronic raw material.
Main technologies: indirect (French) process, direct (American) process, wet process and nano synthesis.
Zinc oxide is an ionic oxide with a wurtzite crystal structure.
Rubber vulcanization: ZnO reacts with stearic acid to form zinc soap, which activates sulfur cross-linking and constructs a stable three-dimensional rubber network.
UV shielding: Its high refractive index enables it to reflect and absorb UVA/UVB radiation.
Antibacterial effect: Photo-generated reactive oxygen species damage microbial cell membranes.
Pigment performance: Its high refractive index provides hiding power.
Indirect process: Zinc ingot → melting → zinc vapor oxidation → cooling and collection → grinding and classification → impurity removal → inspection → packaging.
Direct process: Zinc ore/slag → high-temperature roasting and oxidation → air separation purification → milling → testing → packaging.
Active ZnO: Zinc salt solution reaction → precipitation → washing → calcination activation → milling and sieving.
