Functions and Effects
Pure zinc oxide powder provides strong UV absorption, helping to reduce the impact of ultraviolet exposure in coatings and topical formulations. It acts as a white pigment and opacity enhancer, improving brightness and coverage without relying on organic dyes. Its mild astringent and protective properties make it useful in skin-care and personal-care systems where surface protection and formulation stability are needed. In rubber and polymer applications, it supports vulcanization, heat resistance and mechanical reinforcement. The powder also contributes to antimicrobial stability, moisture resistance and long-term durability in finished products. Its chemical inertness and thermal stability help maintain performance under processing and storage conditions.

Application Fields
Pure zinc oxide powder is widely applied in cosmetics, sun-care products, baby powders, creams and skin-protective formulations. It is used in rubber manufacturing to improve vulcanization efficiency, wear resistance and product durability. In coatings, paints and adhesives, it enhances whiteness, anti-corrosion performance and film stability. The powder is also suitable for ceramics, glass, pharmaceutical intermediates, feed additives and technical laboratory materials. In personal-care and daily-use products, it helps provide a smooth texture, mild surface protection and consistent visual appearance. For industrial buyers, it can be used in masterbatch production, pigment preparation, polymer modification and specialized functional material development.
