Each nylon grade fills a specific performance niche<\/figcaption><\/figure>\n

PA6: The Versatile Workhorse<\/h2>\n

PA6 is the most widely used nylon grade, representing approximately 60% of nylon consumption. It offers an excellent balance of strength, toughness, and processability.<\/p>\n

  • Tensile strength: 70-85 MPa<\/li>\n
  • Excellent impact resistance<\/li>\n
  • Good surface finish and colorability<\/li>\n
  • Wider processing window than PA66<\/li>\n<\/ul>\n

    PA66: The High-Performance Standard<\/h2>\n
    \"PA66
    PA66 dominates under-hood automotive applications<\/figcaption><\/figure>\n

    PA66 offers approximately 10-15% higher strength and stiffness than PA6, with superior heat resistance. It’s the preferred choice for demanding applications.<\/p>\n

    PA11 and PA12: The Specialty Nylons<\/h2>\n

    PA11 and PA12 are distinguished by their exceptionally low moisture absorption\u2014less than 1% even at saturation. This gives them outstanding dimensional stability.<\/p>\n

    \"PA11
    PA11 and PA12 excel in chemical resistance and dimensional stability<\/figcaption><\/figure>\n

    PA46: The High-Temperature Specialist<\/h2>\n

    PA46 (Stanyl) offers the highest heat resistance of any aliphatic nylon, with a melting point of 295\u00b0C.<\/p>\n
