It has a very low thermal conductivity of ??0.030, high quality sheet of 0.028-0.029 (W / mk), compressive strength of ??200kpa, water absorption??0.01, high physical stability, GB / T10801-2002 (Referred to as the standard board) and self-extinguishing flame retardant fire in line with fire standards. Reference price 700-800 yuan / m3. Second, corporate reputation should choose good quality assurance of credit business.
