Rock wool blanket with fiber glass fabric

Rock wool blanket is made of inorganic fiber. It is a good thermal insulation material with low coefficient of thermal conductivity. The products are classified into soft felt, wire fabric felt, fiber glass fabric felt, aluminum foil felt. It is widely used for large and medium tubes, medium and small tanks as well as industrial equipments with arc surface. It has good functions of thermal insulation, sound absorption, dustproofing and waterproofing.
