FireMaster FF 1. is a polybrominated biphenyl containing 2,2',4,4',5,5'-hexabromo- and 2,2',3,4,4',5,5'-heptabromo- isomers as the major constituents. It is a powdered form of FireMaster BP 6 with 2% calcium silicate added to prevent caking.
A white chalky solid. Softens at 162°F.
FireMaster FF 1. is relatively inert . These substances undergo chemical reactions only under relatively severe circumstances or in the presence of an effective catalyst that promotes reaction. They are resistant to ignition, although they may become flammable at very high temperatures. They will be resistant to oxidation/reduction, except in the most severe conditions.
Flash point data for FireMaster FF 1. are not available; however, FireMaster FF 1. is probably combustible.
Confirmed carcinogen
with experimental carcinogenic,
neoplastigenic, and teratogenic data.
Experimental reproductive effects. When
heated to decomposition it emits very toxic
