Ultra-high-molecular-weight polyethylene (UHMWPE or sometimes shortened to UHMW), also known as high-modulus polyethylene (HMPE) or high-performance polyethylene (HPPE), is a subset of the thermoplastic polyethylene. It has extremely long chains, with molecular weight numbering in the millions, usually between 2 and 6 million.

Polystone® M UHMW is a tough, wear resistant plastic that combines an incredibly low coefficient of friction with outstanding impact strength. This self-lubricating polymer has excellent chemical resistance and a broad temperature range making it the perfect choice for engineers in a variety of industries such as conveyor and bulk material handling.

  • Meets FDA and USDA guidelines
  • 3-A Dairy approved (Natural color)
  • Helps to reduce noise
  • Self-lubricating
  • Chemical, corrosion and wear resistant
  • No moisture absorption
  • Non-toxic, low-friction surface

Polystone® M Applications:

  • Chute, hopper and truck bed liners
  • Wear strips and guide rails
  • Star wheels, sprockets and conveyor tracks
