1. High mechanical strength, good toughness, high tensile and compressive strength. Its specific tensile strength is higher than that of metal, and its compressive strength is similar to that of metal, but its rigidity is not as good as that of metal. The tensile strength is close to the yield strength, more than twice as high as ABS. The absorption capacity of impact and stress vibration is strong, and the impact strength is much higher than that of general plastics, and better than acetal resin.
2. Outstanding fatigue resistance, parts after repeated bending can still maintain the original mechanical strength. PA is often used in escalator handrails and new bicycle plastic rims where periodic fatigue is very obvious.
3. High softening point, heat resistance (such as nylon 46, high crystalline nylon thermal deformation temperature is high, can be used for a long time in 150 degrees. After reinforced by glass fiber, the thermal deformation temperature of PA66 reaches more than 250 degrees). 4. Smooth surface, small friction coefficient, wear-resistant. As active mechanical components have self-lubrication, low noise, in the friction action is not too high can not add lubricant use; If you really need to use lubricant to reduce friction or help heat dissipation, water, oil, grease, etc. Thus, as a transmission part, its service life is long.
5 corrosion resistance, very alkali and most salt liquid, but also resistant to weak acid, oil, gasoline, aromatic compounds and general solvents, aromatic compounds are inert, but not resistant to strong acid and oxidizer. It can resist the erosion of gasoline, oil, fat, alcohol, alkali and has good anti-aging ability. Can be used as lubricating oil, fuel and other packaging materials.
6. Self-extinguishing, non-toxic, odorless, good weather resistance, inert to biological erosion, good antibacterial and mildew resistance.
7. Excellent electrical performance. Good electrical insulation, nylon volume resistance is very high, breakdown voltage resistance is high, in dry environment, can be used as working frequency insulation material, even in high humidity environment still has good electrical insulation.
