Zinc Oxide

Zinc Oxide granules is a kind of granular material composed of zinc oxide, usually white in appearance, with a certain particle size distribution, chemically stable, in rubber, ceramics, paints, pharmaceuticals and other fields play a variety of roles, such as rubber vulcanization active agent, ceramic glaze components, paint pigments, and pharmaceutical dressings and so on.

VIMATERIIAL can supply Zinc Oxide granules with purity from 99.9% to 99.995% in the general size of 1-6mm, other specific sizes can be customized. We produce zinc oxide granules with high purity, pure color and low impurities, packaging can be customized, if you need other specifications and sizes, you can contact us, we accept customized service, please feel free to contact us.

Applications

Rubber industry: used as vulcanizing active agent, reinforcing agent of rubber and anti-aging agent of rubber products, it can improve the physical properties of rubber, tear resistance, abrasion resistance, etc., and also accelerate the speed of vulcanization.

Coating industry: It is used as white pigment to provide good covering power and whiteness; it can also be used as ultraviolet absorber to protect the coating and coated objects; it can enhance the anti-corrosion effect in anti-corrosion coatings.

Ceramic industry: It is a flux in ceramic firing process, which can reduce the sintering temperature, and can also be used to prepare ceramic pigments.

Pharmaceutical field: it has antibacterial, anti-inflammatory and astringent effects, and can be used in the preparation of topical drugs for the treatment of skin inflammation, burns, trauma, etc. It can also be used as a medicinal auxiliary material.

Cosmetic field: It is a common sunscreen ingredient, which can effectively block the damage of ultraviolet rays on the skin; it can also be used in foundation, powder and other cosmetics to provide concealment and skin color modification effect.

Electronic industry: It can be used in the manufacture of devices that emit surface acoustic waves, field emitters, sensors, UV lasers and solar cells, etc.; it is also used as varistors and lightning arrestors in electronic products.

Construction industry: The addition of zinc oxide nanoparticles to new types of cement is conducive to improving the compressive strength and antifouling properties of cement-based materials.

Food industry: As an important source of zinc, it is used in food additives, breakfast cereals and feed.

Packing
