Perlite Sandwich Board Application For Building Fire-door Furnaces Cold Insulation

Perlite Board Technical  Parameters:expanded perlite insulation board has 200kg/m3-400kg/m3 low density plates.It is mainly made of the ordinary silicates, glass fibers, foaming agents and other inorganic materials formed,then through the static foaming,conservation to forming.ItermsIndexDensity kg/m3200-380Breaking strength(MPa)≥8Compressive strenth (Mpa)0.35-0.8Thermal conductivity W/(m.k)≤0.035-0.076Water content(%)≤10anti-swelling efficacy(%)≤0.25fire endurance0.6-2hFlame resistant temperature1300°Csound absorption coefficient0.03-0.8Perlite Board Advantage1.
