PA66 (Polyamide 66 or Nylon 66) is more widely used in the automotive industry, instrument housings, and other products requiring impact resistance and high strength compared to PA6. While the chemical and physical properties of Nylon 6 are similar to Nylon 66, it has a lower melting point and a broad processing temperature range. It offers better impact and solvent resistance than Nylon 66 plastics, but also has higher moisture absorption. Due to Nylon 6's tendency to absorb moisture, pre-processing drying is particularly important. If the material is supplied in moisture-proof packaging, the container should remain sealed. If humidity exceeds 0.2%, drying in hot air above 80℃ for 16 hours is recommended. If the material has been exposed to air for more than 8 hours, vacuum drying at 105℃ for over 8 hours is suggested.Broadly used in the manufacturing of mechanical, automotive, chemical, and electrical equipment components, such as gears, rollers, pulleys, shafts, impellers in pump bodies, fan blades, high-pressure seals, valve seats, washers, bushes, various handles, brackets, and inner linings of wire bundles.
