Applications:
Characteristics:
PETS With good heat stability and low volatility under high temperature(TGA shown 400℃ for high grade type PETS-4)
1. PETS can be applied as a highly effective lubricant and dispersing agent in the plastics and rubber industry compared to PE wax or EBS. (e.g., we recommend PETS-3 for use in the compounding of PA6, PA66, and PETS-4 for use in the compounding of PC/ABS, PPO, PPS, PBT, PET, POM, PP, PE, ABS,etc. polymers.),it will mix the main resin with the additive more uniformly without defect spots. Besides this, it also shows easier demolding of the manufactured articles from the molds and improves plasticization, especially PETS-4(1) is the ideal choice of internal and external lubricant for transparent PC compounding.
Dosage:0.1-1phr.
2. It is also a necessary ingredient for compounding Calcium-Zinc heat stabilizers, functioning as internal and external lubricants. Compared with other similar lubricants, it has better heat stability and low volatility.
DosageDosage:3-5phr(relative100PHR PVC).
3. Rubber industry applications,Pentaerythritol tetra stearate is an excellent rubber dispersant and lubricant(similar to the famous types of Struktol WB222 or Aflux 54), can effectively prevent the sticking of the compounds to the rubber rolls, and has a 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. PETS
Dosage: 3-5 phr
4. Oilfield industry application. Pentaerythritol tetra stearate also acts as an excellent lubricant in the oilfield industry, being biodegradable. Several world-famous oilfield service companies are now sourcing this solid lubricant for their compounding of oilfield drilling fluids.
Note:
Pentaerythritol tetra stearate and Pentaerythritol tristearate series have gained REACH pre-registration number and passed SGS inspection concerning SVHC(138 items) and RoHS directives requested by REACH of EU.
