Polyethilene РЕ UHMW 1000
Polipolen®(Polyethilene) is a plastic with a very high molecular weight (molecular chain length). As the molecular chain is long, it is highly resistant against wear&tear. In compliance with with the Sand Slurry wearing test conducted in accordance with the relevant DIN standarts, Polipolen®(Polyethilene) has the highest resistance against wear&tear among all known 1000 class solid materials (steel, wood and other plastics etc.)
Polyethilenes are classified as follows:
PE 1000 ultra high molecular weight polyethilene: those having a molecular weight in excess of 3 million g/mol
PE 500: polyethilenes with a molecular weight in excees of 500.000 g/mol
PE 300 and high density polyethilenes
Low density polyethilenes
