Zinc Oxide (ZnO), a versatile inorganic compound, stands as a cornerstone raw material across numerous industries. NINGBO INNO PHARMCHEM CO.,LTD. is pleased to present its high-purity grade Zinc Oxide powder, meeting stringent quality specifications essential for demanding applications.

Identified by CAS number 1314-13-2, Zinc Oxide is a white solid powder known chemically as an oxide of zinc. It possesses distinct physical and chemical properties that make it indispensable. The powder is characterized by its insolubility in water but readily dissolves in acids and strong bases, demonstrating its reactive nature in appropriate chemical environments. Our product boasts a high purity level, typically exceeding 99.5% ZnO, with minimal impurities like Fe2O3, PbO, CuO, and MnO, ensuring reliable performance in sensitive formulations.

Key physical attributes include a high melting point of approximately 1975ºC and a density of around 5.606 g/cm³. Its excellent thermal stability and non-toxic nature in many forms contribute to its wide usability. As a pigment, it is known as Zinc White, offering good opacity and brightness.

The applications of Zinc Oxide powder are remarkably diverse. In the rubber industry, it serves as a crucial activator for vulcanization, accelerating the process and improving the physical properties of the finished rubber product. The plastics and coatings sectors utilize ZnO for its UV absorption capabilities, acting as a stabilizer to prevent degradation, as well as for its fungicidal properties and pigmentary functions. It is a common additive in paints and coatings to enhance durability and weather resistance.

Furthermore, Zinc Oxide is incorporated into adhesives, ceramics, and even some food applications (as a nutrient supplement). In the pharmaceutical and cosmetic industries, its soothing and protective properties make it a key ingredient in ointments, creams (like calamine lotion), and sunscreens where it provides effective broad-spectrum UV protection.

In the realm of semiconductors, ZnO exhibits a large band gap and high exciton binding energy, leading to excellent room temperature luminescence and high transparency. These properties make it valuable in developing advanced materials for liquid crystal displays, thin film transistors, and light-emitting diodes.

Our Zinc Oxide powder is available in standard industrial packaging, such as robust 25kg bags, designed for safe handling and transport. For large-volume requirements, container load options are efficiently managed, ensuring logistical ease for our global clientele.
