Proprietary Lubricant Pentaerythritol Tetra Stearate (CAS115-83-3)

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. Our PETS has been exporting to South Korea, Japan, India, Turkey, U. S. A., Russia and EU markets directly with competitive prices which applied in the fields of engineering plastics, oilfields, rubber processing.

Applications:

With good heat stability and low volatility under high temperature:

1. PETS can be applied as one high effective lubricant in enginneering thermoplastics (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, POM, ABS GF, PP GF and other polymers as the proprietary external lubricants ) 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. PETS-4 is one excellent rubber dispersant and lubricant(similiar to the famous types of Struktol WB222 or Aflux 54), can effectively prevent the sticking of the compounds to the rubber rolls, and has positive effect regarding flow and demoulding properties with the injection and mould releasing process, most suitable for synthetic rubber, e. G. H-NBR, ECO/CO, FKM, EPDM, CSM, CR, SBR.

3. It is also one necessary ingredient for compounding Calcium-Zinc heat stabilizers which applied in PVC, 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.

4. PETS also acted as one excellent lubricant applied in the oilfield industry which is biodegradeable, several world famous oilfield service company are now sourcing this solid lubricant for their compounding of oilfield drilling fluids.
