Polystone Ultra - Low Friction UHMWPE


Polystone Ultra UHMWPE Product Description:

Polystone Ultra is specifically formulated with improved sliding characteristics improving its resistance to wear, abrasion and environmental stress cracking. Ideally suited to flow promotion and mechanical transmission support products.


Key Features and Benefits of Polystone Ultra UHMWPE:

  • Impact strength - it is virtually unbreakable
  • Light weight - easy to handle without special equipment
  • Physiologically inert - approved for food applications
  • Electrical insulation - it is a good insulator
  • Weatherproof - it doesn't absorb water
  • Chemical resistance - resists corrosive chemicals (Sulphuric Acid, Caustic Soda)
  • Abrasion resistance - rated better than carbon steel for sliding abrasion applications
  • Low coefficient of friction - it does not require lubrication



PE Plastics Applications:

  • Bulk storage flow promotion
  • Bulk storage wear liners
  • Mechanical chain guides
  • Mechanical wear strips
