Zinc Oxide Grade 3A
- Powder type
Grade 3A is the premium grade among our company's zinc oxide product lines, boasting an ultra-high purity of up to 99.8%. Zinc oxide powder is a fluffy white fine powder with unique properties, manufactured through the high-temperature evaporation and oxidation of metallic zinc. Exhibiting excellent heat resistance, it serves as a reinforcing agent in rubber formulations to significantly improve their durability and performance. In the glass manufacturing process, zinc oxide powder acts as an essential flux and effectively counteracts the adverse effects of thermal expansion and contraction. In the electronics industry, zinc oxide powder leverages its unique characteristics; thus, beyond its widespread application in the electronic copying paper market, it is extensively blended as a core ingredient in the raw materials of various electronic components, such as ferrites (electromagnets), semiconductors, and transducers.
