PET is a terephthalate polyethylene based partially crystalline thermoplastic polyester distinguished for a notable hardness. PET offers excellent dimensional stability, even greater than that of POM, since it is practically insensitive to moist environments.
Its good behaviour with gliding combined with a low coefficient of friction and excellent resistance to wear and tear make it the ideal material for mobile parts. Resistance to hot water is low, but it has better resistance to acid than nylon and POM.
