Good chemical resistance and dimensionally stable

Polyethylene terephtalate are Thermoplasticic processed, saturated polyester, which result from terephthalate acid and ethylene-glycol. PET-plas-tics contain high crystallinity and are considered a sliding material with high mechanical strength andexcellent dimensional stability

They are stiff, dimensionally stable and impact resistant at low temperatures. The shape retention in heat, extents close to the melting point of 255 °C. Polyethylene terephtalate are often used as gear wheels, roller bearings or ball bearing shells in machinery cons-truction.
