PET Machinable Plastic Shapes

PET is a general grade unreinforced, semi-crystalline thermoplastic polyester with a relatively high density. It has good mechanical and thermal properties and is resistant to chemicals, solvents, and alcohol. It is often thermoformed for food packaging applications. It has a better impact resistance than acrylic.

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. Ertalyte® retains significantly more of its original strength up to 180°F (85°C) than nylon or acetal.


Trade Names for PET include Ertalyte® and HYDEX®, TECAPET, TECADUR PET
