Product Description
Laurel microporous hard board is ideal for high-temperature insulation material, with a porous structure based on chains of amorphous fumed silica, agglomerates of particles from 7 to 12nm in size. It also contains special opacifiers for minimizing infrared radiation, and inorganic fibers. The hard board has a certain strength and is covered by aluminum foil, PE foil.
