PETS Release Agent
Product Overview
A premium high-temperature lubricant & release agent for engineering plastics
Pentaerythritol Tetrastearate (PETS) is a tetra-ester wax synthesized from pentaerythritol and stearic acid. Compared with conventional EBS or stearate-based lubricants, PETS offers superior thermal stability, lower volatility, and excellent compatibility with high-performance polymers, making it the preferred internal lubricant and mold-release agent for polycarbonate (PC), thermoplastic polyesters (PET, PBT), and other engineering thermoplastics.
PETS minimizes plate-out, gas generation, and screw slippage during high-temperature processing. It is also widely used as a release agent in optical media (CD/DVD), automotive lighting, transparent housings, and food-contact polyolefin films, where clarity, low odor, and minimal migration are essential.
As a PETS release agent supplier, Sychem supplies industrial-grade and high-purity PETS release agent from qualified Chinese manufacturers, with stable supply, batch-consistent quality, and direct factory pricing for global B2B buyers.

Performance Benefits
Engineered for high-temperature engineering thermoplastics
PETS combines the lubrication efficiency of a traditional fatty-acid ester with the thermal robustness needed for PC, PET, PBT, and other resins processed above 280 °C.
01 / THERMAL STABILITY
High-Temperature Performance
Stable up to 290 °C with minimal volatility loss — ideal for polycarbonate, polyester, and other engineering plastics processed at elevated temperatures.
02 / RELEASE
Internal Mold-Release Agent
Reduces sticking in injection molds for transparent and complex geometries — including optical-grade PC parts, lens housings, and thin-wall electronic enclosures.
03 / LOW MIGRATION
No Plate-Out, No Bloom
High molecular weight and tetra-ester structure prevent migration to surface, ensuring excellent printability, paintability, and bonding compatibility.
04 / OPTICAL CLARITY
Transparency Preservation
Compatible with optical-grade PC and SAN — maintains clarity in CD/DVD, automotive lighting, lenses, and medical devices without haze or yellowing.
05 / FOOD-CONTACT
FDA & EU 10/2011 Compliant
Approved for food-contact polyolefin films, beverage closures, and packaging applications, with low odor and minimal extractables.
06 / DISPERSION
Pigment & Filler Wetting
Acts as a dispersing aid in masterbatch production, improving pigment distribution in PC, ABS, and high-temperature filled compounds.
Industries Served
Applications across engineering plastics & specialty polymers
PETS is the lubricant of choice for compounders and OEMs working with high-performance polymers where thermal stability, optical clarity, and low migration are critical.
Polycarbonate Processing
Primary internal lubricant and mold-release agent for transparent PC. Maintains optical clarity in lenses, light covers, electronic housings, and medical devices. Recommended dosage 0.1 – 0.3%.
Thermoplastic Polyesters
Internal lubricant for PET, PBT, PETG, and PCT — improves melt flow, reduces gas defects, and enables smooth demolding of thin-wall and complex parts.
Engineering Plastics
Performance lubricant for ABS, PA, POM, PMMA, and PC alloys. Reduces torque and improves surface finish in glass-fiber-reinforced compounds.
Polyolefin Films & Packaging
FDA-compliant slip and anti-block agent for food-contact PE/PP films, BOPP packaging, and beverage closures. Low odor and excellent organoleptic profile.
Optical Media & Lighting
Specialized release agent for CD, DVD, Blu-ray substrates and automotive lighting (headlamp lenses, reflectors). Maintains sub-micron surface fidelity for optical readability.
Other Specialty Uses
Masterbatch dispersant for high-temperature pigments; powder coating flow promoter; cosmetic emulsifier; high-end candle wax modifier; PVC heat stabilizer co-additive.
Selection Guide
Polymer compatibility & dosage
PETS is most valuable in high-temperature engineering polymers and where transparency, low migration, or food-contact compliance is required.
Typical Dosage Range
Dosages above are general guidelines. Sychem’s technical team can provide tailored formulation support — including high-purity, optical, or food-contact grade selection — based on your end-application.
Comparison
PETS vs EBS — choosing the right lubricant
Both PETS and EBS are widely used as lubricants in plastics processing, but they serve different polymer systems and processing windows.
