1,2-Bis(tetrabromophthalimido) Ethane; Ethylene Bistetrabromo Phthalimide (BT-93);2,2'-(1,2-Ethanediyl)bis(4,5,6,7-tetrabromo-1h-isoindole-3(2h)-dione; 2,2'-(1,2-Ethanediyl)bis[4,5,6,7-tetrabromo-1H-Isoindole-1, 3(2H)-dione; BT 93;BT 93D; 2,2'-Ethylenebis(4,5,6,7-tetrabromoisoindoline-1,3-dione);

Ethylenebis(tetrabromophthalimide) is an additive fire retardant that is added to a polymer mixture to produce a blend. Ethylenebis(tetrabromophthalimide) is used in high impact polystyrene (HIPS), polyethylene, polypropylene, thermoplastic polyesters, polyamide, ethylene propylene-diene terpolymers (EPDM rubbers) and other synthetic rubbers, polycarbonate, ethylene copolymers, ionomer resins, epoxies, and textile treatments.
