ENHANCED POLYAMIDE BASE RESIN FOR ENGINEERING PLASTICS FORMULATIONS

摘要

Polyamide base resins with improved crystallization dynamics for the production of reinforced polyamide compositions having improved surface, shrink, warpage and mechanical properties such as toughness. The polyamide base resins are copolymers of polyamide 6 and polyamide 66, formed of ratios that are tailored to reduce the crystallization rate and final crystallization extent when used in melt processing to produce glass filled articles. The copolymers demonstrate improved polyamide morphology dynamics that in turn impart improved final properties in reinforced molded articles, such as improved surface finish, improved toughness/impact resistance, reduced warpage, and more symmetrical shrinkage properties.
