<p>A liquid formulation of a microporous thermal insulation material comprises an emulsion including an opacifier, a microporous thermal insulating material in a proportion ranging from 10 to 90 percent by weight of the combination of opacifier and microporous thermal insulating material, water, a binder, and a dispersion agent. The formulation may be made by preparing a dry, fibre-free mixture of a microporous thermal insulating material and an opacifier in a proportion ranging from 10 to 90 percent by weight microporous material, and mixing together the dry mixture with water, a binder and a dispersion agent to form an emulsion. A microporous thermal insulation material may be made by impregnating a fibrous mat with the emulsion, and drying the impregnated mat.</p> |
