Annotation

 

This part of ISO 19065 establishes a system of designation for acrylonitrile-styrene-acrylate (ASA), acrylonitrile-(ethylene-propylene-diene)-styrene (AEPDS) and acrylonitrile-(chlorinated polyethylene)- styrene (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.

This part of ISO 19065 is applicable to all ASA, AEPDS and ACS materials consisting of a continuous phase based mainly on styrene-acrylonitrile (SAN) copolymer (in which the styrene component may be styrene itself and/or alkyl-substituted styrene) and a dispersed elastomeric phase based mainly on

— acrylate (ASA materials),

— ethylene-propylene-diene (EPDM) (AEPDS materials),

— chlorinated polyethylene (ACS materials),
