Pentaerythritol stearate (PETS) is a polyol copolymer with excellent internal and external lubrication properties and thermal stability. As a fatty acid ester type environmentally friendly lubricant, it is widely used in various engineering plastic processing processes due to its ability to blend with almost all types of thermoplastic plastics. It can prevent plastic melts from adhering to molds and equipment, and can also ensure smooth demolding of products at high temperatures, Even in molds with complex structures, it can ensure good demolding.

Rubber processing aids play a lubricating, dispersing, and demolding role in rubber processing and mixing, improving the friction force of the rubber material and the adhesion of the drum, and increasing the extrusion rate.

The PETS produced by Sainuo has good internal and external lubricity, which can improve the thermal stability of the product. It has good stability, low volatility, and good demolding and flow performance at high temperatures.

Due to the fact that PETS is a saturated polyol ester without double bonds, it has outstanding thermal stability and low volatility for extrusion or molding processing at high temperatures, without worrying about degradation. At the same time, there are no amide or other chromogenic groups in PETS, and the addition of PETS will not cause color change in the product, which does not affect the transparency of the original product and can also improve the surface smoothness of the product.

PETS is a low dosage internal and external lubricant. Due to the presence of polyol ester groups, PETS can also increase the plasticization performance and stability of engineering plastics or rubber.

PETS has excellent internal demolding and promoting rubber flow performance in rubber or engineering plastic processing, as it can reduce torque, reduce equipment friction, reduce plastic or rubber melt rupture, reduce mold head accumulation, improve plastic or rubber toughness, and make mold filling easier, reducing product defect rates.

PETS is used as a plasticizer and lubricant in the rubber and plastic industries, especially suitable for working conditions that require both thermal stability and excellent demolding performance. Plays a role in plasticization and lubrication during the rubber molding process; It has excellent nucleation effect on partially crystalline plastics and can be used for transparent products;
