• Physical properties: White or pale yellow powder. Slightly soluble in alcohol, ether, almost insoluble in water.
• Uses: Decabromodiphenyl ethane (DBDPE) is a brominated flame retardant used as an additive in a variety of polymer and textile applications. In polymeric applications, such as high impact polystyrene,DBDPE is compounded or blended into the resin. The resulting DBDPE containing plastics are then converted to finished products by, for example, injection molding. For textile applications, DBDPE is blended with various latices and applied as a back coating to the textile.
