  • Patent number: 5719199
    Abstract: A flexible closed cell polymeric foam contains expandable graphite as fire retardant. The foam is prepared by mixing a polymer, a curing agent, at least one blowing agent and an expandable graphite at a temperature of at least 100.degree. C. but below a temperature causing activation of the blowing agent to foam a foamable mixture and thereafter heating the foamable mixture to activate the blowing agent and cause foaming. The method of preparation may additionally include a curing step in which the foamable mixture is heated under pressure to activate simultaneously each of a curing agent, which is preferably a free radical curing agent, and a foaming agent. The foams are capable of meeting the U.S. Federal Aviation Authority Standards, especially the oil burner test of FAR 25 Appendix F, part II.
