Zinc oxide (ZnO) is an inorganic compound used in a wide range of sectors. At James M. Brown, we stock and supply a full range of Zinc Oxide products including those manufactured by Harzer Zinkoxide GmbH (HZO).
HZO zinc oxides are manufactured from the purest and highest quality materials. As a result we supply businesses with premium-quality zinc oxides for applications including pharmaceutical manufacturing, through to commercial grades for the rubber, tyre, and paints industries.
HZO operations are registered to both ISO 9001 (2008) and ISO 14001 (2009), with zinc oxide products available in 25 kg paper sacks, various sizes of FIBCs, powder or pellets.
For expert technical support, express worldwide distribution, and to receive a fast, competitive quote, contact us today to discuss your zinc oxide requirements.
Zinc oxide is an inorganic zinc compound that is insoluble in water and typically appears as a white powder. Zinc oxide occurs naturally as the mineral zincite, though is produced synthetically by businesses such as Harzer Zinkoxide GmbH (HZO) to ensure quality and consistency in high volumes.
The quality and physical properties of zinc oxides are integral to ensure suitability for chosen applications. Factors such as purity levels are vital in pharmaceutical manufacturing where trace levels of impurities can compromise safety standards. The particle size and distribution, particle shape and morphology, and optical properties can further influence suitability of zinc oxides in manufacturing. At James M. Brown, we stock and supply a complete range of zinc oxides, including pharmaceutical grade, cosmetic grade, rubber grade, and pigment grade products to suit your needs.

Zinc oxide (ZnO) is an inorganic compound that appears as a white powder. It’s widely used in various industries due to its unique properties, including UV protection, anti-inflammatory effects, and antibacterial qualities.
There are numerous factors that must be considered when selecting a zinc oxide for your application. For some industries, high purity zinc oxides are vital to maintain quality and safety standards. The particle size (nano-sized or micron-sized), particle shape (e.g. spherical, needle-like), surface area per unit mass, whiteness, brightness are key considerations for many businesses. Companies manufacturing coatings may seek zinc oxides that have consistent and maximum brightness for visual quality control, where pharmaceutical and food manufacturers may prioritise purity levels above other physical properties. If you are unsure of the type and grade of zinc oxide you require, our experts are on hand to provide you with advice tailored to your needs. Contact us today for more information.
Purity levels of zinc oxide are a key indicator of quality, with higher ZnO content and minimal impurities (like heavy metals) products offering the greatest reliability and consistency. Even particle sizings and shapes are key factors in determining the quality levels of zinc oxides.
At James M. Brown, we stock and supply a full range of zinc oxide products manufactured to various grades and specifications to suit your requirements. Contact us today for enquiries and a free, competitive quote.
