Zinc Stearate

Product Description

Zinc stearate is a versatile oleochemical compound, appearing as a white powder and widely used in industry. At CHNV, our zinc stearate is made from plant-based stearic acid and zinc salt, non-toxic, insoluble in water or ethanol, but soluble in hot organic solvents and acids.

Product Features

1. Excellent dispersibility 2. Excellent mold release 3. Excellent thermal stability

Applications

General

Magnesium stearate is an indispensable ingredient in numerous industrial applications such as polymers, polyvinyl chloride (PVC), pencil leads, tablets and cosmetics. It offers chemical stability and can be used as a lubricant, anti-blocking agent, mold release agent and heat stabilizer. Therefore, it is crucial in many industries.

AV300

Stabilizer for PVC products

In addition to its lubricating function, magnesium stearate also acts as a heat stabilizer in the polyvinyl chloride (PVC) industry. During PVC processing, magnesium stearate provides thermal stability from the fuse to the imaging equipment, preventing volatilization and degradation of the material.

Dispersant and lubricant for polymer functional materials

Magnesium stearate has two major functions in the polymer industry: dispersant and lubricant. It helps disperse materials better. It reduces friction between the machine and the material. This improves stability and enhances the quality and functionality of polymer products.

Functional additive for cosmetics and pharmaceutical tablets

As a lubricant and anti-blocking agent, magnesium stearate is commonly used by manufacturers in tablet production. It prevents the powder from sticking together when the manufacturer compresses the capsules. It also improves the appearance of tablets and increases production efficiency. In cosmetic production, magnesium stearate is widely used as a thickener, lubricant and anti-caking agent. You can find it in pressed powders, eyeshadows, blushes and other products. It enhances the texture of cosmetics, making the product softer, smoother and easier to apply. It also improves the stability and overall feel of the product.
