Is Polyurethane Cold Storage Board Fireproof

Polyurethane cold storage board fire, flame retardant, high temperature resistance. After the addition of flame retardants, polyurethane is a flame-resistant self-extinguishing material, its softening point can reach more than 250 degrees Celsius, and decomposition will occur only at higher temperatures. In addition, when polyurethane burns, it forms ash on the surface of its foam, which helps isolate the underlying foam and effectively prevents the spread of the fire. Moreover, polyurethane does not produce harmful gases at high temperatures.
