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
History
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.
Composition
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.
