Patent number: 7863342Abstract: A method for forming a fire resistant material is disclosed. The method comprises providing a plurality of expandable beads of a polymeric material. The beads are coated with an exfoliable graphite. The exfoliable graphite is adhered to the beads with a resin having a solubility parameter of the polymeric material. The beads are thereafter caused or allowed expand and fuse.Type: GrantFiled: June 30, 2010Date of Patent: January 4, 2011Assignee: Synbra Technology B.V.Inventor: David Charles Aslin

Patent number: 7862749Abstract: A free-flowing, stable liquid flame retardant mixture comprised of or formed by mixing together components comprised of: A) at least one organic halogen-containing reactive flame retardant in which the halogen is bromine, chlorine or both; and B) a liquid additive that is comprised of at least one aliphatic polyepoxide of the formula R(EP)n, wherein R is a straight chain or branched chain aliphatic moiety which consists of carbon, hydrogen, and optionally, one or more ether oxygen atoms and/or one or more epoxy oxygen atoms; Ep is a terminal epoxy group: and n is a whole or fractional number in the range of 2 to about 6. Such mixtures can be effectively used in the preparation of flame retardant rigid polyurethanes and rigid foams thereof, and rigid polyisocyanurate and rigid foams thereof. Component B) serves as an effective hardener for such polymers and foams.Type: GrantFiled: May 28, 2004Date of Patent: January 4, 2011Assignee: Albemarle CorporationInventor: Rinus Sjerps
