1, high mechanical strength, good toughness, high tensile strength, compressive strength. The specific tensile strength is higher than the metal, the specific compression strength is about the same as the metal, but its rigidity is not as good as the metal. Tensile strength is close to yield strength, more than twice as high as ABS. The shock, stress vibration absorption capacity is strong, the impact strength is much higher than the general plastic, and is better than acetal resin.
2, outstanding fatigue resistance, the parts after repeated bending can still maintain the original mechanical strength. PA is often used in common escalator handrails and new plastic bicycle rims where the periodic fatigue effect is very obvious.
3, high softening point, heat resistance (such as nylon 46, high crystalline nylon thermal deformation temperature is high, can be used at 150 degrees for a long time. After the glass fiber reinforced PA66, its thermal deformation temperature reaches above 250 degrees).
4, smooth surface, small friction coefficient, wear resistance. As a movable mechanical component when self-lubrication, low noise, in the friction effect is not too high without lubricant use; If you really need to use lubricants to reduce friction or help heat dissipation, then water, oil, grease and other options. Thus, as a transmission component, its service life is long.
5, corrosion resistance, alkali and most of the salt solution is very resistant, also resistant to weak acid, oil, gasoline, aromatic compounds and general solvents, aromatic compounds are inert, but not resistant to strong acids and oxidants. Can resist gasoline, oil, fat, alcohol, alkali and other erosion and has a very good anti-aging ability. Can be used as lubricating oil, fuel and other packaging materials
