Long Chain Polyamides (LCPA) & Alloys for Injection Molded Parts

LCPA & alloys compared to PA6 or PA66:

  • Lower density

  • Higher chemical resistance (e.g. fuel, acids, ZnCl2, coolant)

  • Higher heat resistance (at iso stabilization)

  • Low moisture uptake: dimensional stability and consistent mechanical properties

Long chain PPA compared to PA6T/6X:

  • Higher chemical resistance (e.g. flex fuel, acids, coolant)
  • Can be molded in PA12 molds (same shrinkage)
  • Low moisture uptake (dimensional stability)
