Resumen:
This document establishes a system of designation for poly(phenylene ether) (PPE) thermoplastic materials, which can be used as the basis for specifications. The types of poly(phenylene ether) (PPE) materials are differentiated from each other by a classification system based on appropriate levels of the designatory properties temperature of deflection under load, melt volume-flow rate, charpy notched impact strength, flammability and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. This document is applicable to all PPE materials, including those modified with polystyrene or polyamide or other materials.
