A series of flame retardant additives for ABS have been discussed, including halogen containing flame retardants, as well as halogen free flame retardants. The latter are being preferred for environmental reasons, however, only a few are as effective as halogen containing flame retardants. For ABS blends, some flame retardants (20) have been described that are summarized in Table 8.9.

Suitable fire retardant materials include halogen compounds in combination with antimony compounds, including, tetrabromobis-phenol A and antimony trioxide. Examples for halogen free flame retardants are phosphate esters, such as Hoechst Celanese AP422 or Hoechst Celanese IFR 23.
