Polyester (PET/PBT)

Polyester is a category of polymers which contain the ester functional group in their main chain. Although there are many polyesters, the term "polyester" as a specific material most commonly refers to polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics through step-growth polymerization such as polycarbonate and polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not.

  • Ertalyte PET-P
    Polyethylene Terephthalate (PET) • Extruded Grade •Natural Color
    Ertalyte is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). It is manufactured from proprietary resin grades made by Quadrant. Only Quadrant can offer Ertalyte. It is characterized as having the best dimensional stability coupled with excellent wear resistance, a 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 degreesF and its melting point is almost 150 degreesF higher than acetals. It retains significantly more of its original strength up to 180 degreesF than nylon or acetal. In addition, Ertalyte PET-P offers good chemical and abrasion resistance. Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture. Ertalyte PET-P can be machined to precise detail on standard metal working equipment. See also Ertalyte PET-P Black.

  • Ertalyte TX PET-P
    Polyethylene Terephthalate (PET) • Extruded Grade •Natural Color
    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. Ertalyte TX excels under both high pressure and velocity conditions. It is also ideally suited for applications involving soft metal and plastic mating surfaces. Ertalyte TX is also FDA, USDA and 3A-Dairy compliant.

  • HYDEX 4101
    Polybutylene Terephthalate (PBT) • Extruded Grade •Natural Color
    HYDEX 4101 & 4101L (lubricated) is a very stable chemical compound that can withstand high impact without deterioration. It is approved for direct contact with food by the FDA and is ideal for machined parts in food processing equipment. HYDEX 4101 has excellent resistance to typical cleaning chemicals such as chlorine and caustic solutions and has a very low moisture absorption rate, as much as 15 times less than nylon. See also HYDEX 4101 Black.
