Zinc stearate is a white powder, insoluble in water. Zinc stearate is mainly used as lubricant and release agent for styrene resin, phenolic resin and amino resin. At the same time, it also has the function of vulcanizing active agent and softener in rubber.

Main purpose

It can be used as non-toxic stabilizer for PVC, with small initial coloring and good weather resistance. This product should not be used alone, because it has a significant catalytic effect on the degradation of PVC. After a period of time, the product can change color rapidly. Used with barium cadmium soap for general soft products. The dosage of this product should not be too large, but when used in combination with epoxy compound and phosphite ester, the dosage can be appropriately increased.

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

Metal soap powder. It is used for the creation of fragrant powder and powder. It is mainly used as the adhesive of perfume powder to increase the adhesion of perfume powder on the skin. Zinc stearate is light and soft. When it is added to powder cosmetics, it is coated on other powders, making the powder permeable. The dosage is generally 5% - 15%.

Anti foam agent. Light and heat stabilizers. Paint polish and abrasives. Dry lubricant and isolating agent for feet. Stabilizers, film removers and lubricants for plastic products. Waterproof agent for concrete, brown asbestos, paper and fabric. Used in cosmetics and ointments.

application area 

1. It is used in pharmaceutical industry, the preparation of curing oil and lubricant, and also used as paint drying agent. It is used for processing non-toxic PVC and rubber products. It can effectively improve the photothermal stability of PVC and rubber products with the synergistic effect of calcium stearate and barium stearate. The amount used in PVC processing is usually

2. It is used for rubber products, as well as PP, PE, PS, EPS polymerization additives and pencil lead manufacturing. 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 be used as heat stabilizer of PVC resin.

4. For general industrial transparent products; Used together with calcium soap, it can be used for non-toxic products. Generally, it is used for soft products, but in recent years, it has started to use hard transparent products such as mineral water bottles, water supply pipes and other products. This product has good lubricity, can improve the scaling and precipitation phenomenon, and can also be used as a lubricant, release agent, paint polish agent, and paint additive.
