The main advantages of nylon are as follows:
1. High mechanical strength, good toughness, high tensile and compressive strength. Its specific tensile strength is higher than that of metal, and its specific compressive strength is equal to that of metal, but its rigidity is less than that of metal. Tensile strength is close to yield strength, more than twice as high as ABS. The absorption capacity of impact and stress vibration is strong, the impact strength is much higher than that of general plastics, and better than acetal resin.
2. Outstanding fatigue resistance, the parts can still maintain the original mechanical strength after repeated flexion. PA is often used on escalator handrails and new bicycle plastic wheel reels where the periodic fatigue effect is very obvious.
3. High softening point, heat resistance (such as nylon 46, etc., high crystalline nylon thermal deformation temperature is high, can be used for a long time at 150 degrees. After PA66 is reinforced by glass fiber, its thermal deformation temperature reaches more than 250 degrees).
4. Smooth surface, small friction coefficient and wear resistance. When used as a movable mechanical component, it has self-lubricating property, low noise, and can not be used with lubricant when the friction effect is not too high. If you really need to use lubricant to reduce friction or help heat dissipation, then water oil, grease and so on can be selected. Thus, as a transmission component, its service life is long.
5. Corrosion resistance, very alkali and most salts, but also resistant to weak acid, oil, gasoline, aromatic compounds and general solvents, inert to aromatic compounds, but not resistant to strong acids and oxidants. It can resist the erosion of gasoline, oil, fat, alcohol and weak 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, anti-mildew ability.
7. Excellent electrical performance. Good electrical insulation, nylon volume resistance is very high, high breakdown voltage resistance, in the dry environment, can be used as a working frequency insulation material, even in the high humidity environment still has a good electrical insulation.
8. The parts are light in weight, easy to dye and shape. Due to its low melt viscosity, it can flow quickly. Easy to fill the mold, high freezing point after filling the mold, can quickly finalize the mold, so the molding cycle is short, high production efficiency.
