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 Gaoke has the characteristics of high temperature resistance (the peak temperature resistance reaches 240 ℃), thermal conductivity of 0.034w/(m.k), flame retardancy (B1 level flame retardancy) and easy processing (no fiber chips are produced), which makes it superior to any traditional thermal insulation materials, such as glass wool, rock wool, polystyrene, polyurethane foam, etc. in terms of thermal insulation.
