Ensinger PEI

Global EPP PA 66E Extruded Polyamide 66
Categories: Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 66 (PA66); Nylon 66, Extruded

Material Notes: Polyamides, commonly referred to as nylons, are macromolecular, partially crystalline thermoplastics. Their physical properties are mainly determined by the composition and structure of their molecular chains. Their combined strengths and characteristics position them as obvious first choice materials for all components, subject to structural and wear conditions, in mechanical and plant engineering environments.

Key characteristics:

  • Excellent sliding and wear properties
  • Perfect balance of mechanical strength, toughness and rigidity
  • Good electrical insulating properties
  • Various FDA compliant grades available.

    This grade is noted for its elevated mechanical strength, rigidity, abrasion and heat resistance. Its impact strength and vibration damping abilities are reduced when compared to PA 6, making this the preferred extruded grade for highly stressed, thermally loaded components.
