Documented Uses

• Used formerly as additive flame retardant for polymers; Not commercially produced in the US; [HSDB]
• Used as flame retardant additives in polymers. /Former use/
• Polybrominated diphenyl ethers (PBDEs) are flame-retardant chemicals found in plastics used in a variety of consumer products to make them difficult to burn. Because they are mixed into plastics and foams rather than bound to them, PBDEs can leave the products that contain them and enter the environment. (L628)
• SOME HALOGENATED DIPHENYL ETHERS CAN BE PREPARED BY DIRECT HALOGENATION OF DIPHENYL ETHER CATALYZED BY LEWIS ACIDS & BY DEAMINATION OF NITRO- & AMINO-SUBSTITUTED DIPHENYL ETHERS. /HALOGENATED DIPHENYL ETHERS/
• (1977) NOT PRODUCED COMMERCIALLY IN THE USA
• (1979) NOT PRODUCED COMMERCIALLY IN THE USA
