The fuel barrier PA6 material is developed for the fuel tanks of vehicles and equipment using small engines. Compared with traditional PA6, the fuel barrier performance and impact performance of the fuel barrier PA6 material have been significantly improved. The fuel tank made of fuel barrier PA6 material can meet the recently released and implemented<1.5g/m2 * d volatilization standard by the US Environmental Protection Agency (EPA) and California Air Resources Board (CARB), as well as domestic fuel tank emission standards. Compared with traditional fluorinated HDPE fuel tanks, fuel barrier PA6 fuel tanks do not cause environmental pollution and overcome the disadvantages of complex multi-layer fuel tank forming technology and high equipment investment. Its overall system cost is lower. For a long time, the domestic market for fuel barrier PA6 ma...
