image of Ertalyte PET-P and Ertalyte TX plastic


Ertalyte TX and PET-P have excellent wear resistance and high levels of strength and durability.  They have a low coefficient of friction, and moderate resistance to many types of acid.  Because of their strength and rigidity, it is especially suitable for precision parts sustaining heavy loads. Ertalytes have good chemical and abrasion resistance and has a low moisture absorption.

Ertalyte TX is a variation of Ertalyte PET-P which is internally lubricated.  This solid lubricate gives Ertalyte TX a lower coefficient of friction and wear rate.  It will last close to two times longer than Acetron AF Blend.

Royal Custom Plastics has machine many parts using Ertalyte PET-P and TX.  Bearing blocks, bushings, wearstrips and counterbearings, just to name a few.


Heat & Chemical Resistance

Ertalyte’s continuous service temperature is 210°F (100°C) and its melting point is almost 150°F higher than acetals and has good chemical resistance.


Mechanical properties

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.



Ertralyte is rated HB
