Halogen Free

Brominated Flame Retardants (BFRs) have successfully been used in electronic products for decades to reduce fire-related injury and damage, however many companies have chosen non-Halogen based flame retardants in Printed Circuit Board (PCBs) to meet their performance and sustainability requirements.

While it is not yet legislated that electronic component suppliers must remove brominated and chlorinated flame retardants from their materials, Isola offers a variety of high performance non-halogenated prepregs and laminates to meet the electronic industry’s increased performance demands and marketing requirements for environmentally-friendly designs. Additionally, Isola materials are engineered for thermal reliability to stand up to the rigors of soldering conditions and chemical resistance to survive etching and plating operations.
