Polyethylene Terephthalate – known as PET or polyester — is a thermoplastic polyester that can be amorphous, crystalline, or a mixture of both, depending on how it is processed. All forms provide good chemical resistance and durability.
More about Polyester (PET) »Good for both wet and dry environments
High strength and rigidity – ideal for close tolerance parts
Excellent stain resistance
Good wear resistance and excellent dimensional stability
Better resistance to acids than nylon or acetal
