HYDROLYSIS RESISTANT - HIGH IMPACT POLYETHERIMIDE RESIN BLENDS

摘要

Injection moldable hydrolytically stable transparent thermoplastic Polyetherimide resin blends with high impact and thermal resistance have been developed for healthcare applications. The two-phase resin blends are capable of withstanding 2,500 autoclave cycles at 134°C and 50 ppm morpholine while maintaining clarity and ductility. Injection molding of the new steam resistant blends as well as their rheological and material properties are compared to polyetherimide.
