Polyethylene Terephthalate / PET sheets

In its molecular structure, Polyethylene Terephthalate (PET) sheets are available either as an amorphous or semi-crystalline thermoplastic. Whereas the amorphous type is highly transparent and has a lower mechanical strength, as well as substantially inferior sliding characteristics than the semi-crystalline type, semi-crystalline types have higher hardness, rigidity, and strength with outstanding sliding behavior and low sliding wear (compared to POM in damp or dry environments).

Due to its good creep strength, low moisture absorption, and outstanding dimensional stability, PET is extremely well-suited for applications where complex parts and the highest requirements regarding dimensional accuracy and surface quality are needed.

  • high strength; 
  • high rigidity and hardness; 
  • very low moisture absorption; 
  • very low creep resistance; 
  • very high dimensional stability; 
  • low sliding friction and sliding wear; 
  • resistant to hydrolysis (up to +70 °C); 
  • not suitable for contact with media containing >50% alcohol; 
  • good adhesion and welding ability;
