1. High mechanical strength, good toughness, high tensile and compressive strength. Tensile strength is close to yield strength, more than twice as high as ABS.
2. Outstanding fatigue resistance, the parts can still maintain the original mechanical strength after repeated bending. PA is often used in escalator handrails, new plastic bicycle rims and other occasions where the periodic fatigue effect is very obvious.
3. Smooth surface, small friction coefficient and wear resistance. As a movable mechanical component when self-lubrication, low noise, in the friction effect is not too high without lubricant use.
4. Corrosion resistance, alkali and most of the salt solution, but also resistance to weak acid, oil, gasoline and other solvents, aromatic compounds are inert, can be used as lubricating oil, fuel and other packaging materials.
