Abstract
A fire retarded polymer composition, such as polystyrene polymer, copolymer and/or alloy that comprises heat expandable graphite (HEG) and nitrogen-containing fire retardants (N-FR). The polymer may also be homopolymers of styrene, rubber modified high-impact polystyrenes (HIPS), acrylonitrile-butadiene-styrene copolymers (ABS) or styrene-acrylonitrile copolymers (SAN). The polymer may be an alloy consisting of blends in various ratios of polystyrene polymers and/or copolymers with polycarbonates (PC).
Claims24
A fire retarded polymer composition comprising heat expandable graphite (HEG) and at least one nitrogen-containing fire retardant (N-FR), wherein the polymer component of said composition is selected from the group consisting of polystyrene polymer, copolymer and/or alloy thereof.
