Melacoustic  thermal insulation Foam features an ultra-high porosity rate of over 99%, allowing it to effectively elongate the thermal conductivity path infinitely and thus possess excellent thermal insulation properties. Due to its unique three-dimensional structure, it can effectively hinder the spread of heat through convection, radiation, and conduction. Additionally, the material exhibits stable physical and chemical properties, enabling it to maintain its thermal insulation characteristics continuously in various environments over the long term. With its inherent flame retardancy and excellent secondary processing capability, the material can be applied in various forms for thermal insulation purposes in fields such as mechanical equipment, rail transportation, new energy, construction, and household appliances.
