Ertalyte is an unreinforced, partly crystalline thermoplastic polyester based on polyethylene terephthalate
(PET-P). It is characterized as having excellent wear resistance and a low coefficient of friction, together with high modulus, low creep and superior dimensional stability. Ertalyte’s specific properties make it especially suitable for the manufacture of mechanical precision parts which are capable of sustaining high loads and wear conditions. Eralyte’s continuous service temperature is approximately 10% higher than acetal and its melting point is almost 83°C higher.
In addition, Ertalyte PET-P offers good strength combined with good chemical and abrasion resistance. Its low moisture absorption enables its mechanical and electrical properties to remain virtually unaffected by ambient moisture. These qualities, combined with FDA compliance, make Ertalyte PET-P and excellent candidate for food contact applications. Ertalyte PET-P can be intricately machined using standard metal working equipment.
Ertalyte TX is light grey in colour. It is internally lubricated and has enhanced wear properties.
