Pentaerythrityl tetrastearate CAS NO.115-83-3

With good heat stability and low volatility under high temperature, good mould release property and fluidity; PETS can be used as excellent lubricant in plastics and rubber, oilfield industry. Especially, it is suitable for the situation which requests high heat stability and good mould release.

Pentaerythritol Tetrastearate(PETS-4)PETS-4 can dissolve in solvents, for example ethanol and benzene. Usually is white solid wax in flake or powder form. Product specification：Item PETS-4Acid number(mgKOH/g) 5maxIodine number (gI2∕100g) 2maxHydroxyl number(mgKOH/g) 25~35Saponification number(mgKOH/g) 185~195Melting point(℃) 55~65 CAS No. 115-83-3 Mol. Wt. 1216 Molecular Formula C77H148O8 Note: 1:some physical and chemical properties can be adjusted to client request accordingly.2:This series has passed SGS and REACH inspections.,also have gained the pre-registration number of REACH.Packaging: 25 Kg N.W. per sack (flakes or powder). Storage: Stored in dry and cool places. Shelf life: 1 yearApplications：With good heat stability and low volatility under high temperature: 1. PETS-4 can be applied as one higher effective lubricant and dispersing agent in plastics (e.g. 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 phr2. 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.3. With good heat stability and low volatility under high temperature, PETS can be applied as one high effective lubricant and dispersing agent in compounding the drilling mud fluids.
