Zinc Oxide (ZnO), a white powder with the CAS number 1314-13-2, is a compound of immense industrial significance. Its unique physical and chemical properties make it an indispensable raw material across a surprisingly broad spectrum of applications. As a B2B supplier and manufacturer, we frequently engage with clients seeking to leverage ZnO's capabilities in their formulations and processes. This overview highlights the key sectors where our high-purity Zinc Oxide plays a crucial role.

1. Enhancing Rubber Performance

The rubber industry is one of the largest consumers of Zinc Oxide. It functions primarily as an activator in the sulfur vulcanization process, which cures rubber. ZnO, along with stearic acid, helps to form cross-links, thereby improving the rubber's mechanical strength, elasticity, abrasion resistance, and heat aging properties. For rubber compounders, sourcing consistent, high-purity ZnO is vital for predictable product performance.

2. Advancing Paints and Coatings

In the paints and coatings sector, Zinc Oxide serves multiple functions. It acts as a white pigment, offering good opacity. Crucially, its ability to absorb ultraviolet (UV) radiation makes it an excellent additive for protecting paints and coatings from photodegradation, extending their lifespan and maintaining their appearance. Furthermore, ZnO contributes anticorrosive properties, especially beneficial for metal coatings.

3. Essential in Pharmaceuticals and Cosmetics

The pharmaceutical and cosmetic industries widely utilize Zinc Oxide for its skin-friendly properties. It is a key active ingredient in sunscreens due to its broad-spectrum UV absorption, acting as a physical barrier against UVA and UVB rays. Its anti-inflammatory, astringent, and mild antiseptic qualities also make it effective in topical treatments for skin irritations, diaper rash, acne, and eczema. For these applications, pharmaceutical-grade ZnO with minimal impurities is typically required.

4. Powering Electronics and Advanced Materials

As a semiconductor with a wide band gap, Zinc Oxide has garnered significant attention in the electronics industry. It is used in the manufacturing of varistors (voltage-dependent resistors), gas sensors, transparent conductive films for displays and solar cells, and is being explored for light-emitting diodes (LEDs) and transistors. Its piezoelectric properties also lend themselves to applications in actuators and sensors.

5. Improving Ceramics and Glass

In ceramic manufacturing, Zinc Oxide acts as a flux, lowering the firing temperature and improving the gloss and whiteness of glazes. It enhances the thermal shock resistance and elasticity of ceramic bodies. In glass production, it can increase the refractive index and durability of the glass.
