Plastics. Thermoplastic polyester/ester and polyether/ester elastomers for moulding and extrusion - Designation system and basis for specification Ingestion-build-143074 8 provides you with guidance1 Scope This document establishes a system of designation for thermoplastic polyester ester and polyether ester elastomers, which may be used as the basis for specifications. The types of thermoplastic polyester ester and polyether ester elastomer are differentiated from each other by a classification system based on appropriate levels of the designatory properties: a) hardness; b) melting temperature; c) tensile flexural modulus of elasticity; and on
