UHMWPE: Lightweight & Abrasion Resistant


Key Features of UHMWPE:

  • Excellent strength to weight ratio
  • High abrasion resistance
  • Low specific gravity
  • UV stable
  • Chemically inert except for strong oxidizing acids
  • Resistant to fatigue & internal friction

Ultra-High Molecular Weight Polyethylene (UHMWPE) was first polymerized in the 1950’s.  The first Ultra-High Molecular Weight Polyethylene (UHMWPE) fibers were commercialized in the late 1970’s.  

Ultra-High Molecular Weight Polyethylene (UHMWPE) is a type of polyolefin that is composed of very long chains of polyethylene with a very high % of parallel orientation and high level of crystallinity. 

The extremely long polymer chains enable load transfer by strengthening intermolecular interactions.  UHMWPE fibers are manufactured in a gel spinning process.
