Melamine sponge is a three-dimensional mesh structure. Its open porosity is as high as 99.9%, and its extremely low thermal conductivity makes it an excellent thermal insulation material; it is intrinsically flame retardant - no need to add any flame retardant, and it will form a dense carbonized layer when exposed to fire. The density is only 8-12 kg/m³, the temperature range is -160℃ ~ +240℃, zero formaldehyde, no dust - lightweight, safe and environmentally friendly. One material covers the three core requirements of sound insulation, heat preservation and flame retardancy.
