US: The Polyisocyanurate Insulation Manufacturers Association (PIMA) has opposed the Washington State government’s identification of all organohalogen flame retardants (OFRs) as a priority chemical for additional regulations, including a possible ban. PIMA, along with other industry associations, argues that a blanket treatment of OFRs ignores variations in their chemical structure and risk profiles, thereby complicating efforts to identify safer alternatives while continuing to ensure insulation’s performance and fire safety.
