What is pa material ? PA, polyamide, commonly known as nylon. It is an engineering plastic with excellent performance. It has excellent mechanical properties, outstanding corrosion resistance, oil resistance, heat resistance, high modulus and other advantages. Strengthening and flame retardant modification can significantly improve its heat resistance, modulus dimensional stability and flame retardancy. PA is widely used in automobiles, electronics, electric tools and other industries. The main varieties of PA are PA6 and PA66. Which occupy an absolute dominant position. Followed by PA11, PA12, PA610, PA 612, etc.

Characteristics of PA




  1. Excellent mechanical properties.




Nylon has high mechanical strength and good toughness.


  1. Excellent heat resistance




Highly crystalline nylons such as nylon 46 have high heat deformation temperatures. Which can be used for a long time at 150°C. After PA66 is reinforced with glass fiber, its heat deformation temperature reaches more than 250°C.


  1. Excellent electrical insulation properties




Nylon has high volume resistivity and high breakdown voltage resistance. It is an excellent electrical and electrical insulation material.


  1. High water absorption performance




Nylon has high water absorption, and the saturated water can reach more than 3%. It affects the dimensional stability of the parts to a certain extent.


  1. Good self-lubrication and friction resistance




Nylon has good self-lubrication and low friction coefficient. So it has a long service life as a transmission component and coating material.

Common PA: The difference between PA6 and PA66




  1. Difference in physical properties




Nylon 6 (PA6) is polycaprolactam, while nylon 66 (PA66) is polyhexamethylene adipate. PA66 is 12% harder than PA6, and the chemical and physical properties of PA6 are very similar to those of PA66. However, it has a lower melting point and a wide process temperature range. Its impact resistance and solubility resistance are better than PA66, but its hygroscopicity is also stronger. PA66 is a semi-crystalline-crystalline material with a higher melting point and can maintain strong strength and rigidity at higher temperatures.


  1. Difference in product performance




PA6


Has excellent thermal stability and high heat resistance. The impact resistance and solubility resistance are better than PA66, and the material has good dimensional stability. High surface quality and good anti-warping.

PA66


Has excellent wear resistance, good high impact resistance, and good dimensional stability.


  1. Difference in use




PA6


Generally used in automotive parts, mechanical parts, electronic and electrical products, engineering accessories and other products.

PA66 is widely used in the automotive industry, instrument housings, and other products that require impact resistance and high strength. Such as marine propellers, support frames, wire inner layers, gears, valve seats, gaskets, bushings, various handles, etc.
