PA11 Nylon tube is a synthetic fiber with good physical, chemical and mechanical properties: wear resistance, can be used under conditions of sand and iron filings; smooth surface, reduces resistance, can prevent rust and scale deposition; soft , Easy to bend, easy to install, simple to process. At the same time, it has rigidity. When a certain shape is required, it can be made into various shapes like metal pipes, and does not require complicated equipment and tooling; it can withstand the corrosion of many chemical substances; the size is stable, the permeability is small; the electrical resistance is large, It can be used as an insulator; the service life is very long, even decades; it has good temperature resistance and can work in an environment of -30°C-100°C. Nylon has many characteristics, so it is widely used in automobiles, electrical equipment, mechanical parts, transportation equipment, textiles, and paper machinery. With the miniaturization of automobiles, the higher performance of electronic and electrical equipment, and the acceleration of the process of lightweight mechanical equipment, the demand for nylon will be higher and greater. Especially nylon, as a structural material, puts forward high requirements on its strength, heat resistance, and cold resistance.
