Main uses and application fields of zinc stearate

Zinc stearate is mainly used as lubricant and mold release agent for styrene resin, phenolic resin and amine resin. At the same time, it also has the functions of vulcanization active agent and softener in rubber.

The main purpose

It can be used as a non-toxic stabilizer for polyvinyl chloride, with low initial coloration and good weather resistance. This product is not easy to use alone, because it has a significant catalytic effect on the degradation of polyvinyl chloride, and after a period of time, the product can be rapidly discolored. In combination with barium-cadmium soap, it is used for general soft products. The dosage of this product is not easy to be too large, but when used in combination with epoxy compounds and phosphites, the dosage can be appropriately increased.

It can also be used as a lubricant for styrene resins, including polystyrene, ABS and SAN resins, and as a mold release agent for transparent products. In the rubber industry, this product can be used as a lubricant and a diaphragm agent (anti-sticking) for the rubber compound. also. It can also be used as a textile polish, paint flattening agent and cosmetic ingredients.

Metal soap powder. For the creation of fragrant powder, pressed powder, etc. Mainly used as an adhesive of fragrant powder to increase the adhesion of fragrant powder on the skin. Zinc stearate is light and soft, and when it is added to powder cosmetics, it is coated on the outside of other powders, making the powder easily permeable to water. The addition amount is generally 5%-15%.

Anti-foaming agent. Light and heat stabilizers. Paint flattening agents and abrasives. Small feet drying lubricant and release agent. Stabilizer, release agent, lubricant for plastic products. Waterproofing agent for concrete, asbestos, paper, fabric. Used in cosmetics and ointments.

Application field

1. It is used in the preparation of pharmaceutical industry, curing oil and lubricant, and also used as paint drier. It is used in the processing of PVC and rubber non-toxic products. It has a synergistic effect with calcium stearate and barium stearate, which can effectively improve the light and heat stability of PVC and rubber products. The dosage in PVC processing is usually less than 1 part.

2. It is used for rubber products, and it is also used in the manufacture of PP, PE, PS, EPS polymerization additives and pencil leads. The general dosage is 1~3 parts.

3. Zinc stearate can be used as heat stabilizer; lubricant; grease; accelerator; thickener, etc. For example, it can generally be used as a heat stabilizer for PVC resin.

4. Used for general industrial transparent products; used together 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, water pipes and other products have been used. This product has good lubricity. , can improve the phenomenon of scaling and precipitation, and can also be used as a lubricant, a mold release agent, a flattening agent for paints, and an additive for coatings.
