BTL fiber was founded in beginning of 2011, it was established with an idea from a specialist team who have been working on this product supplier chain more than 10 years, is located in Hangzhou. It is a private enterprise which is specialized in researching and developing, producing and managing UHMWPE(ultra high molecular weight polyethylene fiber) fiber and it's end products. Now it has been developped into a organized company and specialized in all performance fibers.

Ultra-high molecular weight polyethylene fiber (high-strength polyethylene fiber), aramid fiber and carbon fiber are considered as the three major high-performance fbers. Among them, the ultra-highmolecular weight polyethylene fiber has high strength, high modulus, light weight, softness, ultraviolet resistance, impact resistance, acid and alkali resistance, seawater corrosion resistance,etc. It has been widely applied in safety protection, aviation, aerospace, navigation, weapons,shipbuilding, building materials, sports, medical and many other fields, such as body armor,stab-resistant clothing, shields, armored protective barriers for tanks and ships, parachute cables,marine engineering ropes, climbing ropes, deep-sea cages, fishing nets, fishing lines, rowing, sailing,shock-resistant containers, etc., and new applications are constantly being developed.
