Pentaerythritol Tetrastearate (PETS)

Pentaerythritol Tetrastearate (PETS) with long chain fatty acids such as stearic acid, are a class of polymer additives with a strong release effect. They are typically used in polycarbonate and ABS polymers, but also in PET, PA and other plastics. It is recommended for use as a mold release agent in polycarbonate, thermoplastic polyesters and other engineering thermoplastics.

  • Release agent has low volatility
  • Lubricant effect for many polymer compounds in extrusion and molding process
