Melacoustic® hydrophobic melamine foam is a lightweight porous material with an open porosity rate exceeding 99%. It features hydrophobic and oleophobic properties and possesses inherent flame retardancy, as well as excellent sound absorption and noise reduction, thermal insulation, cushioning and shock absorption, and environmental safety. It is widely used as cushioning support material in the fields of new energy batteries and energy storage, as well as in rail transit for cold insulation, flame-retardant and sound-absorbing materials for buildings, pipeline insulation and noise reduction materials, and equipment cushioning and thermal insulation materials.
