Usage Description

Usage and Application: Zinc stearate can be used as a heat stabilizer; lubricant; grease; Accelerator; Thickener, etc. For example, it can generally be used as a heat stabilizer for PVC resin. Used for general industrial transparent products; When used in combination with calcium soap, it can be used for non-toxic products. Generally, this product is mostly used for soft products, but in recent years, hard transparent products such as mineral water bottles and water supply pipes have begun to be used. This product has good lubricity and can improve scaling and precipitation phenomena. It can also be used as a lubricant, release agent, leveling agent for paints, and additive for coatings.

Packaging: This product is packaged in double-layer plastic woven bags lined with plastic film, with a net weight of 20Kg or 10Kg per bag.

Storage and transportation: This product is moisture-proof, rainproof, and sunscreen resistant. It should be stored in a cool and dry place.
