标准范围

ISO 25137-1:20 09建立了砜聚合物模塑和挤出材料的名称系统，包括聚砜(PSU)、聚醚砜(PESU)和聚苯砜(PPSU)，可用作规范的基础。砜塑料的类型通过基于适当水平的指定性质的分类系统彼此区分载荷下挠度的温度，熔体质量流速，夏比缺口冲击强度，拉伸模量和屈服应力，以及关于组成、预期应用和/或加工方法、重要性质、添加剂、着色剂、填料和增强材料的信息。ISO 25137的这一部分适用于所有含有醚氧的砜聚合物，醚氧是聚合物的必要组分，如二苯基砜部分。它适用于未改性或经着色剂、添加剂、填料等改性的粉末、颗粒或小丸形式的可正常使用的砜聚合物材料。

ISO 25137-1:2009 establishes a system of designation for sulfone polymer moulding and extrusion materials, including polysulfone (PSU), polyethersulfone (PESU) and polyphenylsulfone (PPSU), which may be used as the basis for specifications.The types of sulfone plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties

1. temperature of deflection under load,
2. melt mass-flow rate,
3. Charpy notched impact strength,
4. tensile modulus and
5. yield stress,

and on information about composition, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.This part of ISO 25137 is applicable to all sulfone polymers that contain ether oxygen, which is a necessary component of the polymers as in the diphenyl sulfone moiety.It applies to sulfone polymer materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, additives, fillers, etc.
