Flame Retardancy in UL-94 V-0 and in UL-94 5VA High Impact Polystyrene

Abstract

The feasibility of producing HIPS of UL-94 5V flammability rating has been demonstrated. Results of TGA, XRD and SEM enable the role of such components as brominated organic flame retardant, antimony trioxide, chlorin ated polyethylene and magnesium hydroxide in flame retardancy of 5VA HIPS to be evaluated.
