① light weight, corrosion resistance, fatigue cracking, good sealing, small resistance, etc., used to make automobile pipeline, the brake pipe. ② PA11 is ideal for military equipment and new materials, and use it to produce military equipment capability of wet, dry, cold (-40 ℃ or less), heat (up to 70 ℃), dust, water or salty air, can withstand a variety of collision test, used as a stock, grip, trigger guard, the parachute cover. ③ PA11 arc resistance and electrolytic corrosion, is used as wire and cable protection sleeve can improve the reliability and extend the life of the cable; used for undersea fiber optic cable, the protective material of the cable, can reduce the signal loss in the transmission process. ④ PA11 produced when laying the gas pipeline, because of light without lifting device to direct bonding adhesive joints, transportation, operation is very convenient. ⑤ PA11 powder has good melting, adhesion and coating uniformity, in Europe, America, Japan and other countries and regions have been widely used in the garment industry. ⑥ PA11 film is good, used casings with non-toxic, high strength, wear resistance, low permeability and so on.
