Pentaerythritol Stearate Plastic Additives PETS Lubricant For PVC
External Lubricant For PVC Pentaerythritol Stearate PETS
PESS is a high-grade, internal and external lubricants and brightener complex, during a plastic processing applications, .
This product is the latest development of the Guardian music product, compared with market products, PESS biggest advantage is its relative average molecular weight of between 800-1500, than the average fatty acids, alcohols, esters carbon chain much longer, much more , so the biggest feature is the high temperature, good compatibility with the resin. PESS plurality polyol-based, so there is no high or low carbon content of 18 perinatal problems. It is used extensively for PVC resin and other tableting, rolled products, its transparency is its unique properties. Due to the presence of vacancies hydroxy ester PETS single and double, molded plastic article having antistatic properties, PESS is a non-ionic, and other suitable ionizing compounds may become compatible external lubricants, used along with resin-based lubricant inside and outside to make products higher gloss. If the product and short carbon chain polybasic acids or acylated synthesized products can also be used plasticizers, anti-fog, anti-drip.
Rubber industry: rubber mixing process used to sit peptizers, lubricants, add the appropriate oxidizing metal ion compound, and the mold can be greatly reduced friction, reduced mold fouling.
Plastics industry: large number of applications and PVC heat stabilizer lubricant systems, and can be used alone with the processing of PVC.
Alternatively EBS, PE waxes, fatty acids and other lubricant. PESS products it has good thermal stability and the end of volatility, good release properties and liquidity. Especially PESS-3 high temperature, around 260-300 ℃

Plastic Aids PESS-4
Characters: white powder or flake.
Purpose: super excellent PVC, PE inner lubricants, non-toxic, suitable for EPE processing, used as a foaming, anti-shrinkage agents, than individual monoglycerides significantly improve its cost, the proposed amount of 0.5-1%.
Plastic Aids PESS-5
Characters: white powder or flake.
Uses: pure non-toxic lubricant outside, external lubricants for PVC, high temperature, and a variety of commercial stabilizers have good compatibility, the general amount of the stabilizer accounted for 15 --- 25%, when used, supplement plus internal lubricant, but can also be supplemented with other external lubricants. When working directly add recommended amount of 0.5-1.0%. Physical and Chemical Indicators
