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 to expand and fuse.

A composition for forming a fire resistant material comprising a plurality of expandable beads of a polymeric material, wherein the polymeric material comprises 5 polystyrene, said beads being coated with an exfoliable graphite, characterised in that the exfoliable graphite is adhered to the beads with a resin having a solubility parameter of within substantially 0.5 (cal cm−3)1/2 of the solubility parameter of the polymeric material.
A method of forming a fire resistant material comprising:
- providing a composition according to any preceding claim;
- and thereafter causing or allowing said beads to expand and fuse together.
