Ertalyte® PET-P is produced by proprietary resin grades only by Quadrant. Its properties make it especially suitable for the manufacture of precision mechanical parts which are capable of sustaining high loads and enduring wear conditions.

Ertalyte® is semi-crystalline, un-reinforced, thermoplastic polyester based on polyethylterephthalate (PET-P). Ertalyte® is characterized as having high hardness, stiffness, creep and wear resistance, excellent sliding properties in addition to good electrical properties and chemical resistance. Its very low water absorption which hardly influences the mechanical and electrical properties, results, together with a favorable thermal expansion rate, into a very good dimensional stabile material.

Continuous service temperature of Ertalyte® PET-P 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® is FDA compliant in natural and black. Natural Ertalyte® is also USDA, 3A-Dairyand Canada AG compliant.
