A foam composition comprising, A) a cellulose foam matrix, and B) particles of encapsulated organic phase change material which are distributed within the cellulose foam matrix. The invention also relates to a method for making the foam composition and also their use in thermal storage applications, such as air-conditioning units.

Foam composition

A process in which material comprising an aqueous liquid with dispersed particulate solids is pumped as a fluid then allowed to stand and rigidify and the rigidification is improved whilst retaining the pump ability of the material by combining polymeric particles with the material during or prior to pumping the material, wherein the polymeric particles comprise water soluble polymer which has an intrinsic viscosity of at least 3 dl/g. The process of the invention more effectively minimises the area taken up by a stack of the material of given volume whilst maintaining the pumpability of the material. This invention is particularly suited to material that comprises red mud from the Bayer alumina process.
