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. Testing conducted on dry as molded specimen at 73°F Information provided by Nylene® Global Polymer Solutions. |
