标准范围
本文件建立了聚苯醚(PPE)热塑性材料的命名体系,可作为规范的基础。聚(亚苯基醚)(PPE)材料的类型通过基于指定性质的适当等级的分类系统相互区分:a) 荷载下的挠度温度;b) 熔体体积流速;c) 夏比缺口冲击强度;d) 可燃性;以及关于基本聚合物参数、预期应用和/或加工方法、重要性能、添加剂、着色剂、填料和增强材料的信息。本文件适用于所有PPE材料,包括用聚苯乙烯或聚酰胺或其他材料改性的PPE材料。它适用于以粉末、颗粒或丸粒形式准备正常使用的材料,也适用于未经着色剂、添加剂、填料等修饰或改性的材料。这并不意味着具有相同名称的材料必然具有相同的性能。本文件不提供特定应用和/或加工方法所需的工程数据、性能数据或加工条件数据。如果需要此类附加性能,则应根据ISO 20557-2中规定的试验方法(如适用)进行测定。为了指定特定应用的热塑性材料或确保可重复加工,数据块5中给出了要求(见4)。1).
This document establishes a system of designation for poly(phenylene ether) (PPE) thermoplastic materials, which can be used as the basis for specifications.The types of poly(phenylene ether) (PPE) materials are differentiated from each other by a classification system based on appropriate levels of the designatory properties:a) temperature of deflection under load;b) melt volume-flow rate;c) Charpy notched impact strength;d) flammability;and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.This document is applicable to all PPE materials, including those modified with polystyrene or polyamide or other materials.It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc.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 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 20557-2, if suitable.In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, the requirements are given in data block 5 (see 4.1).
