Ertalyte PET-P
Product Profile:
- Good for both wet and dry environments
- High strength and rigidity - ideal for close tolerance parts
- Excellent stain resistance
- Good wear resistance and excellent dimensional stability
- Better resistance to acids than nylon or acetal
- Gamma radiation and arc resistant
Ertalyte is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). It is manufactured from proprietary resin grades made by DSM. Only DSM can offer Ertalyte. It is characterized as having the best dimensional stability coupled with excellent wear resistance, low coefficient of friction, high strength, and resistance to moderately acidic 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. Ertalyte's continuous service temperature is 210°F (100° C) and its melting point is almost 150° F higher than acetals. It retains significantly more of its original strength up to 180° F (85° C) than nylon or acetal.
Ertalyte
TX (PET-P with Solid Lubricant)
Ertalyte TX is an internally lubricated thermoplastic polyester providing enhanced wear and inertness over general purpose nylon (PA) and acetal (POM) products. Containing uniformly dispersed solid lubricant, Ertalyte TX provides a lower wear rate and coefficient of friction than unmodified polyesters like PET or PBT and even internally lubricated materials like Delrin AF blend.
