wallpapers Environment 2020-09-10
Zinc stearate is mainly used as a lubricant and release agent for styrene resin, phenolic resin, and amino resin. At the same time, it also has the function of vulcanization activator and softener in rubber.
The main purpose

1. It can be used as a non-toxic stabilizer for polyvinyl chloride, with low initial colouration 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. After some time, the product can change colour rapidly. It is used with barium cadmium soap for general soft products. The dosage of this product is not easy to be too large, but when it is used in conjunction with epoxy compounds and phosphorous esters, its dosage can be appropriately increased.

2. It can also be used as a lubricant for styrene resin, including polystyrene, ABS and SAN resin, and a release agent for transparent products.

In the rubber industry, this product can be used as a rubber lubricant and diaphragm agent (anti-sticking), also. It can also be used as a textile polishing agent, paint flattening agent and cosmetic ingredients.

3. Metal soap powder.

Used in the creation of powder, pressed powder, etc. It is mainly used as an adhesive of fragrance powder to increase the adhesion of fragrance powder on the skin. Zinc stearate is light and soft, and when added to powder cosmetics, it covers the outside of other powders, making the powder easily permeable. The addition amount is generally 5%-15%.

4. Anti-foaming agent.

Light and heat stabilizers, paint smoothing agents and abrasives, foot drying lubricants and release agents, stabilizers, release agents and lubricants for plastic products. Waterproofing agent for concrete, brown asbestos, paper and fabric. They are used in cosmetics and ointments.

Application field

1. Used in the pharmaceutical industry, the preparation of solidified oils and lubricants, and also as a paint desiccant. 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 amount used in PVC processing is usually less than 1 part.

2. It is used as a rubber compound, and also in the manufacture of PP, PE, PS, EPS polymer additives and pencil cores. The general dosage is 1 to 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 in general industrial transparent products; used with a calcium soap, can be used in non-toxic products. Generally, this product is mostly used in soft products, but in recent years, hard and transparent products such as mineral water bottles, water pipes and other products have been used. This product has good lubricity, Can improve the appearance of scale deposition, and can also be used as a lubricant, release agent, a flattening agent of paint, and additive of colour.
