Product Grades
Industrial Grade
Zinc oxide (ZnO≥95%, coarse particle size) is typically produced via the leaching process of zinc ores. It is widely used in the production of rubber, plastics, paints, coatings, ceramics, and electronic components.
Metallurgical Grade
Zinc oxide (ZnO≥98%, uniform fine particle size) represents an upgrade from the industrial grade, offering enhanced purity and a more consistent particle size distribution. It is suitable for high-end applications, including semiconductor devices, optical instruments, and capacitors.
Medical Grade
Zinc oxide (ZnO≥99.5%, micron-scale particle size) features high purity and fine particle size. It is frequently employed as an additive in pharmaceuticals and in the manufacture of medical dressings.
Food Grade
Zinc oxide (ZnO≥99.8%, nano-scale particle size) is the highest-purity grade among all types. It is used as an additive and nutritional supplement in food and health product applications.
Standard stock items are industrial grade. For special-grade orders, please contact us for full documentation.

Zinc Oxide Used in the Pharmaceutical Industry
In the pharmaceutical field, medical-gradezinc oxide has astringent and skin-protective properties. It can be used in the preparation of ointments, pastes, and other topical formulations to alleviate skin inflammation, eczema, and related conditions.
Zinc Oxide Used in the Cosmetic Industry
Zinc oxide is a broad-spectrum physical sunscreen ingredient that reflects and scatters both UVA and UVB rays in ultraviolet radiation. It is therefore widely used in children's sunscreens, sunscreen products for sensitive skin, and daily skincare products.
Zinc Oxide Used in the Rubber Industry
In the rubber industry, zinc oxide is used to enhance the strength, elasticity, and abrasion resistance of rubber products. It is commonly employed in the production of tires, sealing rings, rubber hoses, etc.
Zinc Oxide Used in the Coating Industry
In the coatings industry, zinc oxide is used as a white pigment to enhance hiding power, improve the anti-aging performance of coatings, and extend their service life. It is suitable for interior and exterior wall paints, industrial anti-corrosion coatings, and other related applications.
Zinc Oxide Used in the Ceramic Industry
In the ceramics industry, zinc oxide also plays an important role, such as improving the glaze quality of ceramic products during production.
Zinc Oxide Used in the Plastic Industry
In the plastics sector, zinc oxide serves as a heat stabilizer to inhibit material degradation, and is particularly suitable for heat-sensitive polymers such as PVC.
Zinc Oxide Used in the Textile Industry
In the textile industry, fibers modified with zinc oxide can be made into antimicrobial fabrics for use in surgical gowns, bed sheets, masks, and other products, providing protection for both medical and everyday applications.
Zinc Oxide Used in the Furniture Industry
In the furniture industry, zinc oxide can be used in wood treatment to prevent mold growth and deformation in humid environments, preserving the aesthetics and durability of furniture.
Zinc Oxide Used in the Food Packaging Industry
In the food packaging field, zinc oxide-modified packaging materials can inhibit the growth of mold inside the packaging, extend the shelf life of food products, and ensure food safety.
Zinc Oxide Used in the Construction Industry
Zinc oxide is also widely used in the construction industry. It possesses excellent corrosion resistance, abrasion resistance, and weatherability, effectively protecting steel structures in buildings from erosion. At the same time, zinc oxide is also a high-quality decorative material that can be used for interior beautification and finishing.
Zinc Oxide Used in the Agriculture Industry
Zinc oxide is also used as a modern pesticide. It serves multiple functions in agriculture, such as promoting plant growth, increasing the nutritional value of plants, and preventing nutrient loss and crop diseases.
Zinc Oxide Used in the Electric Industry
Zinc oxide is used in the production of capacitors, resistors, and transformers for insulation in electronic equipment. Its excellent electrical insulating properties make it an essential material in the electronics industry.
