Product Description

Product Introduction

Zinc oxide is a common white powder, insoluble in water. It's stable under normal conditions but can react with acids and alkalis. This inorganic compound has a high melting point, and its color may turn slightly yellow when heated, then return to white as it cools. It has a fine texture and a metallic - like luster, which gives it useful properties for various industries.

Product Application

• Health and Beauty: Widely used in sunscreens, zinc oxide blocks both UVA and UVB rays to protect skin from sun damage. It's also in many skin creams, like diaper rash ointments, thanks to its ability to soothe irritated skin and prevent bacteria growth.
• Rubber Products: In the rubber industry, zinc oxide speeds up the vulcanization process. This helps make rubber stronger, more durable, and better able to resist heat and wear, especially important for products like tires.
• Paints and Coatings: As a white pigment, zinc oxide gives paints good coverage and helps them last longer outdoors. Some paints with zinc oxide also resist mold and mildew. It can also protect metals from rust when used in anti - corrosion coatings.
• Electronics: Zinc oxide is used to make varistors in electronic circuits. These components protect devices from sudden voltage spikes. It also shows promise for use in LED lights and light - sensing parts.
• Ceramics and Glass: In ceramics, adding zinc oxide to glazes makes them melt at lower temperatures, giving finished pieces a shiny, hard surface. In glassmaking, it can improve the quality and properties of the glass.
