ABSTRACT:
A process for improving the thermal insulation properties of articles such as jackets or slabs made of open cells polymeric foam material is disclosed. A viscous solution is prepared, capable of coating the inner walls of the passages interconnecting the cells. Particles of a size less than the minimum diametrical length of the passages are mixed with the solution. The article is soaked with the mixed solution, squeezed and dried, so that the particles dispersed within the passages partly block the flow of air between adjacent cells.
