In recent years, the demand for flame retardancy of insulation materials has become increasingly high, forcing traditional insulation materials to add harmful and non durable flame retardants to the human body. However, flame-retardant glass wool and rock wool can generate a large amount of fine debris during installation and use, causing discomfort. The melamine sponge produced by Fengtai High tech is resistant to high temperatures (with a peak temperature resistance of 240 ℃)）Thermal conductivity coefficient0.034w/(m.k)、 The characteristics of flame retardancy (B1 level flame retardancy) and easy processing (no fiber chips) make it superior to any traditional thermal insulation materials, such as glass wool, rock wool, polystyrene, polyurethane foam, etc.
