Advantages And Disadvantages Of Nylon Products

Sep 02, 2019

Advantages of nylon products:


1. High mechanical strength, good toughness, high tensile and compressive strength. The specific tensile strength is higher than that of metal, and the compressive strength is comparable to that of metal, but its rigidity is not as good as that of metal. The tensile strength is close to the yield strength and is more than twice as high as ABS. It has strong absorption capacity for impact and stress vibration, and its impact strength is much higher than that of ordinary plastics, and it is superior to acetal resin.


2, the fatigue resistance is outstanding, the workpiece can maintain the original mechanical strength after repeated iterations. PA is often used in the occasions where the escalator handrails and the new bicycle plastic rims are extremely fatigued.


3, high softening point, heat resistance (such as nylon 46, high crystalline nylon high heat distortion temperature, can be used at 150 degrees for a long time. PA66 after glass fiber reinforced, its heat distortion temperature reached 250 degrees or more).


4, the surface is smooth, the friction coefficient is small, wear-resistant. It is self-lubricating when used as a moving mechanical component, and has low noise. It can be used without a lubricant when the friction is not too high. If it is necessary to use a lubricant to reduce friction or help dissipate heat, water oil, grease, etc. can be selected. Thus, as a transmission component, its service life is long.


5, corrosion resistance, very resistant to alkali and most salt liquid, but also resistant to weak acid, oil, gasoline, aromatic hydrocarbon-like 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, weak cockroaches, etc. and has good anti-aging ability. It can be used as packaging materials for lubricating oil, fuel, etc.


 Disadvantages of nylon products:


1. Poor water absorption and poor dimensional stability.


2, poor resistance to low temperature.


3. Antistatic properties are not good.


4, poor heat resistance
