Applications of Pentaerythrityl tetrastearate:

  • In thermoplastic polyester (PET/PBT) has been used as a lubricant such as transparent engineering plastics and dispersant;
  • used in polystyrene (PS) lubricants, release agent and dispersant;
  • used as a polycarbonate (PC) and its alloy release agent, dispersant and lubricant inside and outside;
  • used as polyoxymethylene (POM) and nylon (PA, PA6, PA66) lubricants, release agent and dispersant;
  • used as a thermoplastic polyurethane (TPU) lubricants, release agent, smooth agent and anti mist;
  • used as reinforced polypropylene (PP) plastic lubricants and dispersant, can promote in the glass fiber enhanced engineering plastic glass fiber dispersed in the resin and combination, reduce the leakage, increase the products luster;
  • polymethyl methacrylate (PMMA) of lubricant and anti-sticking agent;
  • high-grade lube oil additives, metal cutting and rolling steel sheet lubricants.
