Material Notes:
PET is an unreinforced, semi-crystalline thermoplastic polyester, demonstrating dimensional stability similar to acetal, combined with the comparable wear resistance of nylon. Heavily loaded mechanical precision components subjected to sustained abrasive environments are particularly suited to this material.Key characteristics:Excellent dimensional stabilityHigh mechanical strength, hardness and rigidityExcellent wear resistanceGood creep resistanceLow moisture absorptionLow thermal expansionGood resistance to radiant energyGood electrical insulating propertiesStain resistantSuitable for food contactThis internally lubricated grade incorporates a uniformly dispersed solid lubricant; demonstrating improved frictional properties, outstanding wear resistance and excellent pressure-velocity characteristics over the basic grade.
