Polyurethane foams with permanent flame retardants offer a new way to pass the well-respected Cal 117 flammability standard. This standard is on the block because of its environmental impact through the historic use of flame-retardants, which have now been found to leave the foam and impact people. The paper will disclose an alternative route to passing this internationally accepted flammability standard which ensures that the flame retardant remains within the foam. The route involves heavy use of recently developed novel green chemistry.
California TB 117 (Cal 117, Cal TB 117) foams have traditionally been made flame resistant by having large amounts of liquid non-reactive flame-retardants added to the other chemicals routinely used to make flexible foams. It has now been determined that these non-reactive flame retardant materials will gradually migrate out of the foam and impact people and the environment. The response of the legislators in California is to propose to cancel the requirement for foams to resist open flame ignition. The thinking being that the foam manufacturer will henceforth no longer need to add these non-reactive flame retardant materials to the foam, thus eliminating future leakage of these materials into the environment.
Green Urethanes disagrees with this direction of travel proposed by the media and the legislators.
