1 Scope

This part of GB/T 38273 specifies the naming system for thermoplastic polyester/ester and polyether/ester elastomers. The basis for setting product specifications. Different types of thermoplastic polyester/ester and polyether/ester elastomers are distinguished by different grades of the following properties. a) hardness; b) Melting temperature; c) Tensile/bending elastic modulus. Information about applications, processing methods, important properties, additives, chroma, filling and reinforcement materials are also related to nomenclature or classification. This section applies to all thermoplastic polyester/ester and polyether/ester elastomers. Suitable for direct use in powder, granular or flake form Used and modified or unmodified materials by colorants, additives, fillers, etc. This section does not mean that materials with the same name must have the same performance. This section does not provide instructions for specific uses and/or special features The engineering data, performance data and processing condition data required for the material of the processing method. When necessary, it is necessary to comply with Part 2 of this standard The verification methods specified in determine these additional properties. In order to illustrate the special purpose of a certain thermoplastic or to guarantee the reproducibility of processing, additional requirements can be given in character group 5 (see 4.1).
