Full Name
Polyester Ertalyte or PETP
Basic Properties
High mechanical strength, stiffness & hardness. Wear resistance is better than that of Nylon grades. Insulates well against electricity and resistant to acid. Suitable for contact with food & is physiologically inert.
Common Uses
With very similar properties to Acetal, this product is used in precision gears, bushes, bearings and mechanical components. It has a high operating temperature with good dimensional stability.
