Yes, these are used as flame retardants in some plastics. Check with the resin manufacturers, they should know about it. GE Plastics for instance, has published a document stating which plastics have the PBBs.
Darrell Locke Advanced Input Devices ---------- From: Crane, Lauren To: [email protected]; [email protected] Subject: PBBs (Polybrominated Biphenyls), and PBDEs (polybrominated diphe nyl ethers). List-Post: [email protected] Date: Wednesday, November 03, 1999 8:56AM The European Commission is contemplating a directive (the WEEE directive) that, in its current draft, will require a phase out of the use of some substances typically found in electronic devices, including PBBs (Polybrominated Biphenyls), and PBDEs (polybrominated diphenyl ethers). I wonder if these chemicals are the ones typically used to provide printed circuit boards with their flame retardant qualities (i.e. UL 94-V0 rating). Does anyone out there know?
