Zinc oxide
Zinc oxide is a fundamental inorganic chemical powder material with an extremely broad range of applications. Thanks to its stable chemical properties and multifunctional characteristics, it is used across numerous industries, including rubber and plastics, coatings and ceramics, personal care and pharmaceuticals, feed processing, and water treatment. When selecting materials for production, many companies require raw materials with consistent purity and controllable impurity levels, while also hoping that a single raw material can be adapted to multiple product lines. Zinc oxide is ideally suited to meet these diverse production needs.
In terms of its inherent properties, zinc oxide appears as a fine white powder; it is non-toxic, odorless, and chemically stable, offering multiple functions such as light-blocking and sun protection, vulcanization and activation, antibacterial and preservative effects, as well as reinforcement and filling. As a white pigment, it offers excellent coverage and outstanding weather resistance, with strong resistance to UV degradation. When added to coatings and plastics, it not only adjusts color and enhances whiteness but also delays material aging and fading. In rubber and plastic systems, it serves as a key vulcanization activator, accelerating the vulcanization reaction rate and improving the tensile strength, abrasion resistance, and anti-aging properties of the finished products; At the same time, zinc oxide possesses antibacterial and astringent properties. Grades that meet regulatory standards can be used in topical ointments and skincare ingredients, and it can also be applied as a trace element additive in livestock and poultry feed to supplement zinc and promote growth and metabolism. Thanks to its excellent compatibility, zinc oxide can be blended with the vast majority of powders and additives, making it adaptable to adjustments in various formulation systems and easier to use.
Jiurunfa classifies zinc oxide into multiple grades based on different application scenarios, ensuring targeted compliance with various industry standards and preventing waste caused by users making uninformed product selections. High-purity indirect-process zinc oxide features high purity, uniform reactivity, and superior dispersibility, making it suitable for high-demand applications such as high-end rubber products, weather-resistant exterior wall coatings, electronic additives, and pharmaceuticals and personal care products. Impurity levels are strictly controlled to ensure they do not interfere with the product’s core performance; The economical direct-process zinc oxide offers outstanding value for money and is suitable for routine production applications such as ceramic glazes, general-purpose plastic fillers, industrial additives, and feed additives, ensuring basic performance while controlling production costs. Every product undergoes comprehensive physical and chemical testing before shipment, with precise control over key indicators such as purity, fineness, heavy metals, and moisture content, effectively preventing common issues such as batch-to-batch color variations, fluctuations in activity, and caking due to moisture absorption.
In addition, Jiurunfa provides comprehensive guidelines for use, storage, and transportation: We recommend storing the product in a sealed container in a dry, well-ventilated warehouse, away from humid environments and acidic materials, to prevent moisture absorption and agglomeration that could affect dispersion. For different processing methods—such as mixing and grinding—we provide guidance on feeding methods and recommended addition rates to help customers quickly optimize formulations, reduce trial-and-error costs, and lower defect rates. Whether customers are placing large-volume routine orders or requesting small-batch samples or customized specifications, they can receive corresponding technical support.
Unlike the homogenized, low-end raw materials commonly found on the market, Jiurunfa implements closed-loop control throughout the entire process—from raw material procurement, synthesis reactions, and grinding and screening to finished product filling. The company strictly controls pollutant emissions at every stage of production, ensuring that all product specifications comply with relevant national industry standards while balancing performance requirements with environmental compliance.
