The PA tube is a kind of pneumatic tube that is often used in daily life. What are the unique advantages of this tube? The following is a professional PA tube manufacturer to introduce to you.
1.PA pipe has high mechanical strength, good toughness and 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, and the original mechanical strength can be maintained after repeated bending of the workpiece. PA is often used in occasions where the periodic fatigue of the escalator handrails, new bicycle plastic rims, etc. is extremely obvious.
3. PA tube has high softening point and heat resistance (such as nylon 46, high crystalline nylon has high heat distortion temperature and can be used for a long time at 150 degrees. After PA66 is reinforced by glass fiber, its heat distortion temperature reaches 250 degrees or more) .
4. Smooth surface, low friction coefficient and wear resistance. 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. Therefore, as a transmission component, its service life is long.
5. PA tube is corrosion resistant, very resistant to alkali and most salt liquid. It is also resistant to weak acid, engine oil, gasoline, aromatic hydrocarbon-like compounds and general solvents. It is 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.
6. Self-extinguishing, non-toxic, odorless, weather resistant, inert to bio-erosion, good antibacterial and anti-mildew ability.
7. PA tubes have excellent electrical properties. The electrical insulation is good, the volume resistance of nylon is very high, and the breakdown voltage is high. In the dry environment, it can be used as a power frequency insulation material, and it has good electrical insulation even in a high humidity environment.
8. The parts are light in weight, easy to dye and easy to form. It can flow quickly due to its low melt viscosity. Easy to mold, high solidification point after filling, quick setting, so short molding cycle and high production efficiency
