no_pic_available
PE-UHMW | PE 1000 | Ultra high molecular weight polyethylene

Semi-crystalline thermoplast | Technical plastic

Characteristics: Very high wear resistance, low coefficient of sliding friction, very high impact strength, low density, virtually no moisture absorption, limited weldability, resistance to exceptionally strong impacts, outstanding chemical resistance, self-lubricating characteristics, good stress crack resistance, can be used to a temperature limit of -200°C, food safe (FDA)

Very good resistance to acids, bases, alcohol, aldehydes, organic solvents, and grease
Limited resistance (swelling) to some hydrocarbons
No resistance to strong oxidants such as fuming sulfuric acids, concentrated nitric acids, nitrosulfuric acids, chromosulfuric acids and halogens, and some cleaning agents.
Risk of formation of stress cracks.

Typical applications:  Slide parts, linings, chain guides, curved guides, bushings
