NYLENE 421 HS
TECHNICAL DATA SHEET

 
General Description    

  • Impact modified, heat stabilized nylon 6 injection molding resin.
  • Nylene 421 HS has the inherent heat and chemical resistance typical of nylon 6 resins, while having higher toughness for uses where impact may occur during service
  • Suitable for such applications as clips, fasteners, safety restraint components, and uses which require higher toughness and flexibility
