Performance advantages

PA66 has excellent mechanical properties, electrical properties,wear resistance, chemical resistance and lubricity. However, due tothe existence of amido group in nylon, it can form hydrogen bondwith water molecules and has greater water absorption, resulting inpoor dimensional stability of the product and affecting electricalproperties. Low impact strength, creep resistance and heatresistance in dry or low temperature also need to be improved.Compared with steel, it has the advantages of corrosion resistance,self lubrication, low relative density and easy forming.Disadvantages: large water absorption and insufficient mechanicalproperties. Therefore, as an engineering structural material, itsperformance must be improved to meet the requirements of industrialuse
