What is UHMWPE fiber?

The UHMWPE fiber (Ultra High Molecular Weight Polyethylene Yarn) has 15 times stronger than steel and 40% stronger than aramid when weight for weight basis. It is the strongest yarn today for making cut-resistance gloves, high-strength ropes, and bulletproof fabrics. Its tenacity at breaking up to 45g/D and has goods performance on anti-UV, anti-chemicals, and anti-cut. Introduce of Ultra High Molecular Weight Polyethylene Yarn The Ultra-high-molecular-weight polyethylene (UHMWPE fiber) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene (HMPE yarn), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million annual. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made. UHMWPE fiber is odorless, tasteless, and nontoxic. It embodies all the characteristics of high-density polyethylene (HDPE) with the added traits of being resistant to concentrated acids and alkalis, as well as numerous organic solvents. It is highly resistant to corrosive chemicals except for oxidizing acids; has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating (see boundary lubrication); and is highly resistant to abrasion, in some forms being 15 times more resistant to abrasion than carbon steel. Its coefficient of friction is significantly lower than that of nylon and acetal and is comparable to that of polytetrafluoroethylene (PTFE, Teflon), but UHMWPE fiber has better abrasion resistance than PTFE. UHMWPE yarn is also one of three major hi-tech fibers ( specifically the carbon fiber, aramid, and UHMWPE fiber), in addition, it is a super-strong polyethylene fiber that offers maximum strength combined with minimum weight. It is up to 10 times stronger than quality steel and up to 40% stronger than aramid fibers, both on weight for weight
