Chinber Watch Accessories Stretchy Loop Nylon Elastic Bracelet Wristbands for iWatch 42mm/44mm Strap

Nylon benefits:

1. High mechanical strength, good toughness, high tensile and compressive strength. The specific tensile strength is higher than that of metal, and the specific compression strength is not the same as that of metal, but it is less rigid than metal. The tensile strength is close to the yield strength, which is more than twice as high as ABS. The absorption capacity of shock and stress vibration is strong, and the impact strength is much higher than that of general plastics, and is better than acetal resin.

2. The fatigue resistance is outstanding, and the original mechanical strength can be maintained by repeated bending of the parts. PA is often used in the cases where the escalator handrail and new bicycle plastic wheel ring have obvious periodic fatigue effect.

3. The heat deformation temperature of PA66 is over 250 ℃ after glass fiber reinforced.

4. The surface is smooth, the friction coefficient is small and the wear resistance is low. When working as movable mechanical components, it has self-lubricating property and low noise. When the friction effect is not too high, it can be used without lubricant; if lubricant is really needed to reduce friction or help heat dissipation, water oil, grease, etc. can be selected. Thus, as a transmission part, its service life is long.

5. It is corrosion resistant, very alkali resistant and most salt solutions, and also resistant to weak acids, oil, gasoline, aromatic hydrocarbons and general solvents. It is inert to aromatic compounds, but not strong acids and oxidants. It can resist the corrosion of gasoline, oil, fat, alcohol, weak alkali and so on, and has good anti-aging ability. It can be used as packing material for lubricating oil, fuel, etc.
