ActivePlastics—Polystyrene (PS) moulding and extrusion materials—Part 1:Designation system and basis for specifications
塑料 聚苯乙烯（PS）模塑和挤出材料 第1部分：命名系统和分类基础
Application Summary AI generated
This standard establishes a designation system for polystyrene (PS) moulding and extrusion materials, classifying them by key properties such as Vicat softening temperature, melt mass-flow rate, and impact strength. It is applied in the plastics manufacturing industry to provide a uniform naming and specification basis for PS resins used in injection moulding, extrusion, and sheet production. The standard ensures consistent material identification and quality control across suppliers and end-users in sectors like packaging, consumer goods, and construction.
