ABS is used
where somewhat higher impact strength and other engineering properties
are required. It gives a good surface appearance and therefore has
applications in computer housings and office machine housings and
components. It is readily flame retarded with brominated flame retardants.
In order to maintain the flow properties for processing and the
impact properties for the end-use applications, melt-blending brominated
fire retardants are chosen. Where UV stability is a priority, selecting
the appropriate brominated fire retardant, pigment package, and
UV and processing stabilization package are critical.
Where a
non-halogen flame retardant is required, ABS requires another polymer
such as PC to achieve the UL-94 V-O flammability requirement. These
are generally referred to as PC/ABS as the PC is present in higher
concentration than the ABS. The addition of this polymer changes
the processing conditions for injection molding as well as compounding
resulting in higher costs for this type of system.
