Abstract:
1. A rigid thermal insulation and/or buoyancy material that is constituted by a mixture of: a) a matrix of a homogeneous mixture of cured elastomer polymer and a liquid insulating plasticizer compound, said insulating plasticizer compound being selected from compounds derived from mineral oil, and compounds derived from vegetable oils, said insulating plasticizer compound not being a material of the type that changes phase at a temperature lying in the range −10° C. to +150° C., the mass proportion of said plasticizer compound in said matrix being at least 50%; and b) hollow beads, dispersed within a said matrix of said homogeneous mixture of said polymer and said insulating plasticizer compound, at a proportion by volume of at least 35% of the total volume of the mixture of said beads with said matrix.
