Product index

Pentaerythritol stearate (PETS, dividing into PETS-3, namely pentaerythritol tristearate and PETS-4, namely pentaerythritol tetrastearate) can dissolve in solvents, for example ethanol and benzene. Usually is white solid wax in flake or powder form.

 Product application

With good heat stability and low volatility under high temperature:

1.PETS can be applied as one higher effective lubricant and dispersing agent in plastics (e.g. we recommend PETS-3 to be used in the compounding of PA6,PA66,UPVC, PETS-4 to be used in the compounding of PC/ABS,PP,PET,PBT,POM,ABS GF,PP GF and other polymers) and rubber industry comparing with PE wax or EBS, it will mix the main resin with the adding agent more uniformly without defect spot occurred, Besides this, it also show easier demoulding of the made-up articles from the Molds, can notably lower the surface tension with the resins and improve the plasticization. Dosage:0.5-1 phr;

2.It is also one necessary ingredient for compounding Calcium-Zinc heat stabilizers, functioning as the internal and external lubricants, comparing with other same lubricants, have better heat stability and low volatility. The dosage of PETS is 3~5phr.
