CSA Group Plastics - Acrylonitrile-styrene-acrylate , acrylonitrile- -styrene and acrylonitrile- -styrene moulding and extrusion materials - Part 1: Designation system and basis for specifications ISO 19065-1:2014

ISO 19065-1:2014 establishes a system of designation for acrylonitrile-styren e-acrylate (ASA), acrylonitrile-(ethyl ene-propylene-diene) -styrene (AEPDS) and acrylonitrile-(chlor inated polyethylene)-styren e (ACS) moulding and extrusion materials, which may be used as the basis for specifications. The types of ASA, AEPDS and ACS plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties: a) Vicat softening temperature, b) melt volume-flow rate, c) Charpy notched impact strength, d) tensile modulus, and on information about composition, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.
