NATURAL PET

PET SERIES

NGM-T12

PET: English name Polyethylene Terephthalate , is an engineering plastic profile made of crystalline thermoplastic polyester. Hard, good stiffness, high strength, toughness, small friction coefficient, high dimensional stability.

 

KEY PROPERTY:

Mechanical strength, stiffness and hardness. Good sliding performance and wear resistance, good electrical insulation, very good creep resistance, low and stable friction coefficient excellent wear resistance (better compared with nylon), very good dimensional stability (better than POM), physiological inertia ((suitable for contact with food).
