Melacoustic foam panel + aluminum foil + backing adhesive melamine high-speed rail cold-proof material is a lightweight porous material with an open porosity rate exceeding 99%. It possesses inherent flame retardancy and excellent properties such as sound absorption and noise reduction, thermal insulation, cushioning and shock absorption, and environmental safety. It is widely used as flame-retardant and cold-proof material in high-speed rail, EMU, subway, and other rail transit systems. By compounding with smooth and flat aluminum foil, the overall physical strength and insulation performance are further enhanced.
