Porous silica composite material for thermal insulation To obtain excellent insulation effect, heat insulating material should have the capacity to inhibit the solid heat transmission, convection and radiation. The porous silica composite material for thermal insulation of our co***ny has such capacity. The lower density of the solid material, the lower heat conductivity it owns. To reduce material density, general heat insulating material turn to getting a lot of pores. Our material is the best one...
