Pentaerythritol Tetrastearate (PETS) is a high-performance ester-type lubricant offering excellent thermal stability and low volatility during processing. Its balanced internal/external lubrication profile makes it a preferred choice in engineering plastics where surface quality and optical clarity matter.
PETS is commonly used where standard metallic soaps or fatty amides are unsuitable, particularly in applications sensitive to plate-out or where food-contact and low-odour requirements apply.
Key Benefits
- Excellent thermal stability at high processing temperatures
- Low volatility, reduces plate-out and die build-up
- Balanced internal and external lubrication
- Supports high-clarity, high-gloss finishes
- Low odour and food-contact friendly grades available
