PET

PET is a material for engineering plastics with polyethylene terephthalate resin as a raw material and has a high dielectric strength, dimensional stability, and excellent stick-slip performance.
PET100 basic grade (white)
PET200 stick-slip grade (gray)

Applications

bearing, thrust washer, guide, food processing machine head, piston, feed screw, roll, case, jig and components that are in contact with food, bush for precision machine, electrical insulation material, etc.
