Pentaerythritol Stearate PETS-4 as internal and external lubricant for PVC, PP, PE, PBT, PA, PU etc
August 17, 2023
How to use PETS-4 for plastic industry.
Pentaerythritol Stearate PETS-4. It has good internal and external lubricant, can improve the thermal stability of the product, and is non-toxic. The product is usually a white hard high melting point wax, soluble in solvents such as ethanol, benzene, and chloroform.
PETS is an ester product with excellent thermal stability, which slowly decomposes when the pyrolysis weight reaches 400 ℃. It has very little volatility and can be widely used as a lubricant in various engineering plastic processing processes. It can prevent the fusion of plastic from adhering to molds and equipment. At the same time, it can ensure smooth demolding of products in high-temperature environments, even in complex structure molds, ensuring good demolding performance. In addition, during the feeding process, it can prevent melting (bridging phenomenon) in the raw material area. It is beneficial for improving the injection molding feeding and filling speed, enabling the product to achieve a smooth surface and high smoothness. It has excellent nucleation effect on partially crystalline plastics and can be used for transparent products.
Application of PETS in PVC:
.PETS acts as a lubricant, release agent, antifogging agent, and antistatic agent in PVC.
.The addition of PETS in hard PVC injection molding can significantly reduce the tensile strength and Rockwell hardness of the product. It will significantly increase the impact strength and yield elongation of the product.
.PETS conforms to the influence of ordinary lubricants on the mechanical properties of hard PVC injection molded products.
.PETS can significantly improve the processability of hard PVC and is an excellent internal lubricant, while also having an external lubrication effect.
Application of PETS in PE/PP PETS:
.Serve as an antistatic agent, lubricant, dispersant, and antifogging agent.
Application of PETS in ABS:
.PETS can greatly improve the processing flowability of ABS engineering plastics.
Application of PETS in PBT/PET:
PETS can be used as an environmentally friendly high-temperature anti adhesion agent with excellent thermal stability and minimal volatility.
Application of PETS in polyurethane (PU):
.PETS acts as a refreshing and anti fogging agent.
Application of PETS in modified PA6 and PA66:
.PETS can be used as a high-temperature lubricant and anti glass fiber exposure agent for both internal and external balance in product processing.
Application of PETS in other fields:
.PETS acts as a lubricant, plasticizer, and release agent in the rubber molding process.
.PETS can be used as a thickener in the field of oilfield drilling chemicals.
