What are the properties of UHMWPE?
UHMWPE has good mechanical, physical and tribological properties, such as: extreme hardness and durability, good chemical resistance, abrasion resistance, impact resistance, being easy to fabricate, a very low coefficient of friction and being a non-polarity polymer [6–12].
What is UHMWPE fiber?
High-performance ballistic fibers Ultra-high molecular weight polyethylene (UHMWPE) fibers are the strongest and lightest fibers available, due to their combination of high strength and low density.
What is the yield strength for UHMWPE?

What material is UHMWPE?
UHMW (ultra high molecular weight polyethylene) is an extremely tough plastic with high abrasion and wear resistance. The versatility of polyethylene has made it a popular plastic for countless industrial applications that require durability, low friction, and chemical resistance.
Why is UHMWPE so strong?
UHMWPE is a type of polyolefin. It is made up of extremely long chains of polyethylene, which all align in the same direction. It derives its strength largely from the length of each individual molecule (chain).
Is UHMWPE same as Dyneema?
UHMWPE (ultra high molecular weight polyethylene) rope is an extremely tough plastic with high abrasion and friction resistance. It’s a superior alternative to steel wire rope and is used in maritime, lifting and high friction industries. It’s chemically and physically identical to Dyneema.
Is UHMWPE stronger than steel?
This means that UHMWPE fibres has an incredibly high tensile strength compared to many other thermoplastics, and this also means that the material is much stronger than steel in the fibre direction.
