perlite fire board

perlite fire board : fireproof door core sizes:915mm*2135mm 600mm*800mm thickness:25~50mm

  perlite fire board

1. FeaturePerlite fire door core is consisting of expanded perlite and inorganic glue. With the chatacters of light(kow bulk density), high hydrophobe rate , high strength, low thermal conductivity and easy-to use, Hydrophobel perlite board/ tiles are widely used in roof, wall, barns  as core of wooden fire door and steel fire door.

 

2. Main performance

1) Thermal conductivity: 0.03 ~ 0.076 W/(m.k)
