Product details

Zinc powder is a dark gray powdered metallic zinc that can be used as a pigment and has strong covering power. It has excellent rust prevention and resistance to atmospheric erosion. Commonly used as a pigment for paint and a filler for rubber.

Zinc oxide is an additive in the rubber and tire industry, and is also used as a vulcanizing activator, reinforcing agent, and coloring agent for natural rubber, synthetic rubber, and latex. If ordinary zinc oxide is made into nano zinc oxide and used in rubber, it can fully exert the vulcanization effect and enhance the performance of rubber, with a dosage of 30% to 50% of ordinary zinc oxide.

In the electronics industry, zinc oxide is not only the main raw material for varistor, but also the main additive for magnetic, optical and other materials. The use of nano zinc oxide to prepare varistors has a lower sintering temperature and improved varistor performance, such as flow capacity and nonlinear coefficient. The application of nano zinc oxide in optical devices will make significant breakthroughs with the in-depth study of its optical properties.
