White powder / bead Zinc stearate - Qingdao Sainuo

2022-05-13

Zinc Stearate is widely used as lubricant and release agent of styrene resin, phenolic resin and amine resin. It is used as softening lubricant of rubber products, textile polishing agent, stabilizer of PVC plastic, paint and enamel smoothing agent, and raw materials of cosmetics. Zinc Stearate of  Sainuo  can be divided into two forms according to the mesh number, fine powder and granular , it has Inhibit initial coloring, avoid vulcanization pollution, good lubricity, mold release and adhesion.

This product has the characteristics of high purity, transparency and good thermal stability. At the same time, it has been proved that the product quality index and application effect are up to or better than similar imported products. It is a heat stabilizer and lubricant for the processing of plastic raw materials, plastic color masterbatch, engineering plastics and rubber compounds.

Molecular formula: Zn (C17H35COO)2

Physicochemical properties: white light powder, specific gravity 1.095, greasy, insoluble in water, soluble in hot organic solvents such as ethanol, benzene and turpentine, and decomposed into stearic acid and corresponding zinc salt in case of strong acid.

1. The test shows that the product quality index and application effect are up to or better than similar imported products. It is an environmental friendly heat stabilizer and lubricant for the processing of plastic raw materials, plastic color masterbatch, engineering plastics and rubber compounds.

2. 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. For general industrial transparent products; Combined with calcium soap, it can be used for non-toxic products. Generally, it is mostly used for soft products. It has good lubricity and can improve the scaling and precipitation phenomenon. It can also be used as lubricant, release agent, smoothing agent of paint and additive of coating. It is mainly used as lubricant and release agent for styrene resin, phenolic resin and amine resin. At the same time, it also has the functions of vulcanizing activator and softener in rubber.

3. It can be used as a non-toxic heat stabilizer for PVC, with good initial coloring inhibition and lubricity, and no vulcanization pollution, but the thermal stability is limited. The formed zinc chloride has catalytic degradation effect on PVC and is generally not used alone. It is mostly used in combination with stabilizers such as calcium soap and barium soap, and is mainly used for soft products. In water-based coatings, it has the function of increasing sliding and grinding. It is an indispensable accelerator in foaming products.

4. Good lubricity, which can improve the phenomenon of scaling and precipitation. It can also be used as lubricant, release agent, leveling agent of paint and additive of coating.

5. It has the characteristics of high purity, good transparency and good thermal stability.

6. Generally, it can be used as the heat stabilizer of PVC resin. For general industrial transparent products; Combined with calcium soap, it can be used in environmental protection products. Generally, this product is mostly used in soft products, but hard transparent products such as mineral water bottles and water pipes have been used in recent years.

Because the high proportion of this product in PVC processing will cause "zinc burning", some auxiliary stabilizers need to be added to the composite formula. For general PVC formula, low zinc combined with heat stabilizer should be used.

The difference between zinc stearate and stearic acid

Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles and films. It is a PVC heat stabilizer with good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps prevent "coking" during processing, It is an effective heat stabilizer in PVC film processing, and can prevent the discoloration of finished film caused by exposure to sulfide. Stearic acid plays an important role in the synthesis and processing of rubber. In the production of synthetic rubber, stearic acid needs to be added as emulsifier. In the manufacture of foam rubber, stearic acid can be used as foaming agent, and stearic acid can also be used as release agent for rubber products. In addition, it can also be used as solvent for oil-soluble pigments, crayon sliding agent, wax paper polishing agent, emulsifier of stearic acid glyceride, etc.
