多层尼龙管有两层、三层、四层和五层多层管等多种，外径为6-32mm等不同规格。PA多层复合管能有效降低汽车排放物对环境的污染，满足更高的环保要求。同时多层复合管具备优良的耐渗透性能。随着汽车轻量化、节能减排发展要求，以及新能源汽车渗透率逐年提升，多层尼龙管在汽车上的应用越来越广泛，主要类型有：
-冷却系统用三层直管（PA/TIE/PP&TPV）
-冷却系统用三层三层波纹管（PA/TIE/PP）
-燃油系统用2/3/5层直管/波纹管(PA/TIE/EVOH/TIE/PA)
其中用于新能源汽车冷却系统三层直管/波纹管是目前主流的发展方向，市场潜力很大。
Multi-layer PA tube has 2 layers, 3 layers, 4 layers and 5 layers of multi-layer tube,6-32mm outside diameter range PA multilayer composite tube can effectively reduce the pollution of automobile emissions to the environment, meet the higher environmental protection requirements, and has excellent permeability resistance With the development requirements of automotive lightweight energy conservation and emission reduction, as well as the increas ing penetration rate of new energy vehicles year by year, multi-layer nylon tube/hose are more and more widely used in automobiles.The main types are as follows:
- 3-layer straight tube for cooling system(PA/TIE/PP&TPV)
-3-layer corrugated tube/hose for cooling systems(PA/TIE/PP)
-Fuel circuit system with 2/3/5 layer straight/corrugated tube/hose(PA/TIE/EVOH/TIE/PA)
Among them, the three-layer straight/corrugated hose used in the cooling system of new energy vehicles is the mainstream develop ment direction at present, and the market potential is huge
