This part of ISO 2580 establishes a system of designation for acrylonitrile/butadiene/styrene (ABS) thermo-plastic materials, which may be used as the basis for specifications.
The types of ABS 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) Izod impact strength
d) flexural 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 2580 is applicable to all acrylonitrile/ butadiene/styrene materials (in which the styrene
component may be styrene itself and/or an alkyl-substituted styrene), consisting of a continuous phase based mainly on copolymers of styrene (and/or an alkyl-substituted styrene) and acrylonitrile, a dispersed elastomeric phase based mainly on polybutadiene, and other components in such quantities as specified in data block 1.
It applies to ABS materials ready for normal use in the form of powder, granules, pellets or chips, unmodified or modified by colorants, additives, fillers, etc.
