Material Notes:
Linear, saturated polyesters are thermoplastics which are used where good dimensional accuracy, high creep resistance and good sliding and wear behavior are required. Partially crystallized PET possesses high hardness, strength at high temperatures and resistance against stress cracking.Information provided by Hippe.
