The UHMWPE fiber, short for PE fiber, has extreme long chains, with molecular weight numbering in millions. The long chain gives its high specific strength, high elastic modulus, low specific gravity, low shrinkage, perfect fastness to chemical agent, perfect weatherability, high energy absorption, X-ray transparent, low electric conductivity and seawater corrosion resistance. The fiber has widely used in personal armor, vehicle armor, cut-resistant gloves, bow strings, climbing equipment, fishing lines, spear lines for spearguns, high-performance sails, suspension lines on sport parachutes and paragliders, rigging in yachting, kites and kites lines for kites sports.
