Product Details
Polyamide (PA), commonly known as nylon, is one of the most widely applied engineering plastics. It is primarily utilized in synthetic fibers, with its most prominent advantage being superior abrasion resistance compared to other fibers—10 times higher than cotton and 20 times higher than wool. Incorporating even a small proportion of polyamide fiber into blended fabrics can markedly enhance their wear resistance. Featuring non-toxicity, lightweight properties, excellent mechanical strength, outstanding abrasion resistance and favorable corrosion resistance, polyamide is extensively adopted as a substitute for metals such as copper. It is widely used to manufacture bearings, gears, pump impellers and other components across the machinery, chemical, instrumentation and automotive industries.

Features
Nylon, as a widely used engineering plastic, is extensively used in machinery, automobiles, electrical appliances, textile equipment, chemical equipment, aerospace, metallurgy, and other fields. It has become an indispensable structural material in various industries, and its main characteristics are as follows:
1. Excellent mechanical properties. Nylon has high mechanical strength and good toughness.
2. Good self-lubricating and friction resistance. Nylon has excellent self-lubricating properties and a low coefficient of friction, thus resulting in a long service life for transmission components.
3. Excellent heat resistance. Highly crystalline nylons such as Nylon 46 have very high heat distortion temperatures and can be used for extended periods at 150℃. PA66, after being reinforced with glass fiber, has a heat distortion temperature exceeding 250℃.
4. Excellent electrical insulation properties. Nylon has high volume resistivity and high breakdown voltage, making it an excellent electrical and electronic insulation material.
5. Excellent weather resistance.
6. Water absorption. Nylon has high water absorption, with saturated water content reaching over 3%. This can affect the dimensional stability of parts to some extent.
