塑料.热塑性聚酯（TP）模塑和挤压材料.第1部分:命名系统和规范基础

[中文适用范围]： 本文件为热塑性聚酯（TP）材料建立了一个分类系统，可作为规范的基础。 该范围涵盖基于聚对苯二甲酸乙二醇酯（PET）、聚对苯二甲酸丁二醇酯（PBT）、聚环己二甲基对苯二甲酸酯（PCT）、聚乙萘二甲酸酯（PEN）、聚丁萘二甲酸酯（PBN）和其他类型的热塑性聚酯以及各种成分的共聚酯，用于成型和挤出。 根据适当的分类性质水平区分热塑性聚酯的类型：a) 粘度数；b) 抗张模量。 [外文原描述]： This document establishes a system of designation for thermoplastic polyester (TP) material, which can be used as the basis for specifications. It covers polyester homopolymers for moulding and extrusion based on poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT), poly(cyclohexylenedimethylene terephthalate) (PCT), poly(ethylene naphthalate) (PEN), poly(butylene naphthalates) (PBN) and other TP-types and copolyesters of various compositions for moulding and extrusion. The types of thermoplastic polyester are differentiated from each other by a classification system based on appropriate levels of the designatory properties: a) viscosity number; b) tensile modulus of elasticity; and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. This designation system is applicable to thermoplastic polyester homopolymers and copolymers. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, fillers and other additives. This document does not apply to the saturated polyester/ester and polyether/ester thermoplastic elastomers covered by ISO 20029. 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 can 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 20028-2, if suitable. In order to designate a thermoplastic polyester material to meet particular specifications, the requirements are to be given in data block 5 (see 4.1).
