ISO 20029-1:2017建立了热塑性聚酯/酯和聚醚/酯弹性体的命名体系,可作为规范的基础。
热塑性聚酯/酯和聚醚/酯弹性体的种类通过基于适当水平的指定性质的分类体系彼此区分:
a)硬度;
b)熔化温度;
c)弹性的拉伸/弯曲模量;
以及关于预期应用和/或加工方法,重要性能,添加剂,颜色,填料和增强材料的信息。
ISO 20029-1:2017适用于所有热塑性聚酯/酯和聚醚/酯弹性体。它适用于粉末,颗粒或颗粒形式的正常使用的材料,未经改性或由着色剂,填料或其他添加剂改性。
这并不意味着具有相同名称的材料必然具有相同的性能。本文档不提供工程数据,性能数据或可能需要指定材料的工艺条件数据。如果需要这些附加属性,则按照ISO 20029-2中规定的测试方法(如果合适)进行测定。
为了指定符合特定规格的热塑性聚酯/酯或聚醚/酯弹性体,要求在数据块5(见4.1)中给出。
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).
