Changing a Winning Team—Replacement of Brominated Flame Retardant and Antimony Trioxide in Acrylonitrile–Butadiene–Styrene

ABSTRACT This study examines two comprehensive approaches to reducing the amount of antimony trioxide (ATO) in brominated flame retardant (tris(2,4,6‐tribromophenoxy)‐s‐triazine bromine) (Br) in acrylonitrile–butadiene–styrene (ABS). One approach systematically substitutes Br/ATO with magnesium hydroxide (MH), while the other substitutes ATO with calcium borate, zinc borate, zinc oxide, zinc sulfide, and zinc stannate. We investigated the pyrolysis (thermogravimetry), flammability (limiting oxyg
