Basic Information about Pentaerythrityl Tetrastearate (PETS)
Pentaerythrityl Tetrastearate (PETS) is white hard high melting-point wax, soluble in ethanol, benzene.
Uses:
1. Plasticizer, in the process of rubber plastication plastic solution and lubrication role. 2. Stabilizer is used for PVC and other polymers used for the processing and stabilizer, plasticizer and lubricant inside.
3. Lubricants are used in high-grade lube oil additives, metal cutting and rolling steel sheet of the lubricant.
In the process of extrusion and mold processing, PETS for many polymers are a performance with excellent additives. For example in the enrichment of filler masterbatch, masterbatch, flame retardant masterbatch formula, can promote pigments, fillers or flame retardant evenly dispersed; In glass fiber enhanced engineering plastics can promote glass fiber dispersed in the resin and combination, reduce the leakage, increase the products luster. PETS outstanding thermal stability, make it can be used for high temperature processing of such a system, and don't have to worry about is degraded in the processing course.
PETS have good thermal stability and low volatility at high temperature; good demoulding and flow performance; for part of crystalline plastics have excellent nucleation effect: can be used for transparent products.
As PC, hard PVC, and other polymer system outside the lubricant, the efficiency of PETS, allowing it to use less than most traditional lubricant, typical dosage of 0.1 ~ 1% when you need to have a combination of performance, thermal stability and excellent demoulding PETS is a good choice.
