The primary benefits of PA6 nylon plastic supplies:
1. Excessive mechanical energy, good toughness, excessive tensile and compressive energy. The particular tensile energy is increased than that of metallic, and the particular compressive energy is corresponding to that of metallic, however its rigidity is not so good as that of metallic. The tensile energy is near the yield energy, greater than twice as excessive as ABS. The flexibility to soak up shock, stress and vibration is powerful, and the affect energy is way increased than that of common plastics, and is best than acetal resin.
2. Excellent fatigue resistance, the elements can preserve the unique mechanical energy after repeated inflections. Frequent escalator handrails, new bicycle plastic rims and different events the place periodic fatigue is extraordinarily apparent, PA is commonly used.
3. Excessive softening level and warmth resistance (corresponding to nylon 46, and many others., excessive crystalline nylon has a excessive warmth distortion temperature and can be utilized for a very long time at 150 levels. After PA66 is strengthened with glass fiber, its warmth distortion temperature can attain 250 levels or extra).
4. The floor is clean, the friction coefficient is small, and it’s wear-resistant. It’s self-lubricating when it’s used as a movable mechanical element and has low noise. It may be used with out lubricant when the friction will not be too excessive; if lubricant is admittedly wanted to scale back friction or assist warmth dissipation, water, oil, grease, and many others. could be chosen. Because of this, it has an extended service life as a transmission element.
5. Corrosion resistant, very proof against alkalis and most salt options, additionally proof against weak acids, engine oils, gasoline, fragrant compounds and common solvents, inert to fragrant compounds, however not proof against robust acids and oxidants. It may resist the erosion of gasoline, oil, fats, alcohol, weak base, and many others. and has good anti-aging skill. It may be used as packaging materials for lubricating oil and gas.
6. It’s self-extinguishing, non-toxic, odorless, good climate resistance, inert to organic erosion, and has good antibacterial and antifungal capabilities.
7. It has glorious electrical properties. Good electrical insulation. Nylon has a excessive quantity resistance and excessive breakdown voltage. It may be used as an influence frequency insulating materials in a dry surroundings, and it has good electrical insulation even in a excessive humidity surroundings.8. The elements are gentle in weight, straightforward to dye and straightforward to form. Due to its low soften viscosity, it might probably move rapidly. It’s straightforward to fill the mildew, the solidification level is excessive after the mildew is crammed, and the form could be set rapidly, so the plastic machining has a brief molding cycle and excessive manufacturing effectivity.
The primary disadvantages of PA6 nylon plastic uncooked supplies:
1. Straightforward to soak up water. The water absorption is massive, and the saturated water can attain greater than 3%. To a sure extent, it impacts the dimensional stability and electrical efficiency, particularly the thickening of thin-walled elements has a larger affect; water absorption may even vastly scale back the mechanical energy of the plastic. When deciding on supplies, consideration needs to be given to the affect of the use surroundings and the accuracy of coordination with different elements. Fiber reinforcement can scale back the water absorption fee of the resin, in order that it might probably work beneath excessive temperature and excessive humidity. Nylon has an excellent affinity with glass fiber. It’s generally used to make machining uhmw combs, toothbrushes, garments hooks, fan bones, internet bag rope, fruit outer packaging baggage and so forth. Non-toxic, however not long-term contact with acid and alkali. It’s value noting that after including glass fiber, the tensile energy of nylon could be elevated by about 2 instances, and the temperature resistance could be improved accordingly.
2. Poor gentle resistance. In a long-term excessive temperature surroundings, it would oxidize with oxygen within the air, and the colour will flip brown at first, after which the floor shall be damaged and cracked.
3. The injection molding expertise necessities are strict: the presence of hint moisture will trigger nice injury to the molding high quality; the dimensional stability of the product is tough to manage because of thermal enlargement; the existence of sharp corners within the product will trigger stress focus and scale back the energy of CNC mechanical parts; If the wall thickness will not be uniform, it would trigger distortion and deformation of the elements; the precision necessities of the CNC machining factory gear are very excessive throughout the post-processing of the elements.4. It is going to swell by absorbing water and alcohol. It’s not proof against robust acids and oxidants, and can’t be used as acid-resistant supplies.
