  • Fireproof enclosure
    Patent number: 8472189
    Abstract: An enclosure comprises a thermal barrier (42) for protecting a heat sensitive component (40). The thermal barrier includes at least one endothermic layer (48, 54, 58) that includes water gelled with a thickening agent, absorbed onto a cellulose-comprising fabric or paper. The endothermic layer is sandwiched between layers comprising metal foil or sheet (49, 52, 56).
    Type: Grant

  • Fire resistant materials
    Patent number: 7863342
    Abstract: 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.
