Ertalyte® ~ PET-P

Ertalyte ® is an unreinforced semi-crystalline thermoplastic polyester based on polyethylene teraphalate (PET-P).  Ertalyte ® PET-P offers dimensional stability coupled with excellent wear resistance, low coefficient of friction, high strength, and resistance to moderate acid solutions. Ertalyte’s properties make it especially suitable for the manufacture of precision mechanical parts which are capable of sustaining high loads and enduring wear conditions.


  • Excellent wear resistance
  • Excellent dimensional stability
