High molecular weight polyethylene or HMWPE has a molecular weight about 10 times higher (usually between 3.5 and 7.5 million amu) than High Density Polyethylene (HDPE) resins. It is synthesized using metallocene catalysts and ethane units resulting is structure where ethane units are bonded together resulting in HMWPE structure typically having 100,000 to 250,000 monomer units per molecule.
It has excellent mechanical properties such as high abrasion resistance, impact strength and low coefficient of friction. The material is almost totally inert, therefore it is used in the most corrosive or aggressive environments at moderate temperatures. Even at high temperatures, it is resistant to several solvents, except aromatic, halogenated hydrocarbons and strong oxidizing materials, such as nitric acid.These special properties allow the product to be used in several high performance applications.
HMWPE is suitable for high wear applications such as tubes, liners, silos, containers and other equipments.
Applications:
Food processing equipment
Water treatment
Conveyor lines
Wear strips
Bearings
Gears
Pistons
Valves
Marine equipment
Wet environments that require regular harsh cleaning
