Problems solved by technology

The "B1 grade EPS board" that appears on the market is made by melting the flame retardant and polystyrene particles and then making the particles into foam molding. While achieving the flame retardant effect, its thermal conductivity is as high as 0.040w / m·k , is not conducive to the application of EPS board
