塑料.聚醚醚酮（PEEK）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]： 本文件规定了聚醚醚酮（PEEK）模塑和挤出材料的命名系统，可作为规范的基础。聚醚醚酮聚合物链由苯环在(1,4)位置通过两个乙 ether 组重复后的一个酮基连接而成。根据适当的表征性质（a）熔融粘度或熔体体积流动速率；b）拉伸模量；c）拉伸强度；以及关于 intended application 和/或 processing method、重要性能、添加剂、染料、填料和增强材料的信息，PEEK 塑料等级通过分类系统相互区分。命名系统适用于所有聚醚醚酮。它适用于未经过任何 modification（如染色剂、填料、增强材料或其他 additive）的粉状、颗粒或丸状形式 ready for normal use 的材料。本文件不旨在暗示具有相同命名的材料必然具有相同的性能。本文件不提供工程数据、性能数据或加工条件数据，这些数据可能需要根据特定应用和/或加工方法来指定一种材料。如果需要额外的性质，则建议根据 ISO 23153-2 中 specified 的试验方法进行确定。为了为特定应用或确保可重复加工指定热塑性材料，附加要求在数据块 5 中给出（见 4.1）。 [外文原描述]： This document establishes a system of designation for polyetheretherketone (PEEK) moulding and extrusion materials which can be used as the basis for specifications. Polyetheretherketone polymer chains are composed of phenylene rings linked in (1,4) position by a sequence of two ether groups followed by one ketone group. The grades of PEEK plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties a) melt viscosity or melt volume-flow rate; b) tensile modulus; c) tensile strength; and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. The designation system is applicable to all polyetheretherketones. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colourants, fillers, reinforcements or other additives. It is not intended to imply that materials having the same designation necessarily give 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 for a particular application and/or method of processing. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 23153-2, if suitable. In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements are given in data block 5 (see 4.1).
