CNBM new fireproof rock wool sandwich board uses twolayer high quality colored steel sheet or other precision profiled metal plate as the panel board.

After the board is rolled and shaped, stripped rock wool should be turned 90°(make its fiber perpendicular to upper and lower steel sheets),

and then fire resistant bond with high strength and cohesion should be used for bonding the high quality rock wool with the metal panel together, thereby composing beautiful, smooth and rigid building board. The shaped board has excellent fire prevention, thermal insulation and environmental protection features and provides one superexcellent choice for industrial building enclosure system.
POILISOCYANURATE, abbreviated as PIR; composite boards developed by DUOWEI use excessive sulfone isocyanurate, so ring structure of chemical compound and higher sulfone isocyanurate index form the dense PIR, thereby making interior rigid foam more stable and have high heat resistance and flame resistance. Experiment shows that the bubble can endure 200 ℃ in a short time and can endure 160℃ in a long time.
