Melacoustic® FT5 melamine foam is a lightweight porous material with a density of 5.5KG±1.5, featuring an open porosity rate exceeding 99.4%. It possesses inherent flame retardancy and excellent properties such as sound absorption, noise reduction, thermal insulation, cushioning, shock absorption, and environmental safety. Its extremely low density makes it widely used in aerospace for thermal and acoustic insulation, in rail transportation for cold-proofing materials, and in interior decoration and battery insulation for new energy vehicles.
