Ertalyte (PETP)

Ertalyte PETP is a proprietary product manufactured from proprietary resin grades and is available in rod, tube or sheet form.


Ertalyte and ErtalyteTX are both semi-crystalline thermoplastic polyesters and is FDA approved. It is classed as a stain resistant plastic and has very low moisture absorption.


Ertalyte properties allow mechanical and electrical characteristics to remain virtually unaffected by moisture making this material ideally suited as a bronze bush replacement.


Ertalyte PETP properties make it especially suitable for the manufacture of precision mechanical parts capable of sustaining high loads in challenging wear conditions.


PETP has similar properties to Acetal, with benefits and features such as:

  • Improved tensile strength
  • Dimensional stability
  • Operating temperature
  • Physiologically inert
  • Reduced notched impact resistance


Applications of Ertalyte PETP products include:

  • Precision gears and bearings
  • Thrust washers
  • Pump components
  • Slideways
  • Components for mechanisms of precision, etc
