Ultra-high-molecular-weight polyethylene - Wikipedia

Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene.Also known as high-modulus polyethylene, (HMPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions.

UHMWPE has less creep than other fibers like polyester. If creep is of high concern - perhaps in the manufacture of recurve bowstrings - a UHMWPE grade with a higher modulus could be the best fit. UHMWPE also has significantly better UV resistance than aramid yarn and tends to be a better choice for outdoor applications.
