ISO 20029-1:2017 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 information about the intended application and/or method of processing, important properties, additives, colour, fillers and reinforcing materials.ISO 20029-1:2017 is applicable to all thermoplastic polyester/ester and polyether/ester elastomers. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colourants, fillers or other additives.It is not intended to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which may be required to specify a material. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 20029-2, if suitable.In order to designate a thermoplastic polyester/ester or polyether/ester elastomer to meet particular specifications, the requirements are given in data block 5 (see 4.1).

Le présent document établit un système de désignation des élastoméres thermoplastiques à base de polyester/ester et polyéther/ester qui peut être utilisé comme base pour les spécifications. Les types de thermoplastiques à base de polyester/ester et polyéther/ester sont différenciés les uns des autres par un système de classification basé sur des niveaux appropriés des propriétés de désignation (dureté température de fusion, module d'élasticité en traction/en flexion) et sur des informations concernant l'application prévue et/ou la méthode de mise en oeuvre, les propriétés importantes, les additifs, les colorants, les charges et les matériaux de renfort. Le présent document est applicable à tous les élastomères thermoplastiques à base de polyester/ester et polyéther/ester. Il s'applique aux matériaux près à l'emploi sous forme de poudres, grains ou granulés, non modifiés ou modifiés par des colorants, charges, ou autres additifs.
