In the field of insulating material, phenolic plate and extruded board are more common insulation products, phenolic board known as the king of the insulating material, but the application of extruded board also is quite widespread, so phenolic board and what is the difference between extruded board, the following a few two products to make parsing.



in the first place, the duct products generally are the same, but the phenolic board and extruded board fire performance difference is bigger, phenolic board fire rating in b1 level, fire performance of composite at A2 level, extruded board fire rating of the b1 level is the highest.



both is not much difference in appearance, with the hand to touch the side of the plate can feel the toughness of phenolic board worse than extruded board, best method is to use open flame lit, to tell which characterize the changes, phenolic insulation board in case of fire don't burning carbonization, black carbon, meet flame is melted to form the plastic cloth extruded board, burning phenomenon, obviously, on the other hand also can distinguish from the smell and extruded board, phenolic board



on the other hand can also distinguish between phenolic plate from the smell and extruded board, phenolic board without the smell of smoke no irritant gas combustion, extruded plate burning there will be a small amount of smoke and stimulating odour gas, with a little words simply how to distinguish between phenolic plate and extruded board is very simple, very convenient also, reminded many customers bought from money. Don't buy phenolic board extruded board. Phenolic composite insulation board suitable for duct, and the rubber insulation pipe is the difference between the construction is convenient, short time limit, beautiful and easy lifting a molding, and the price is much cheaper.



the place on put together is narrated, is through from flame-retardant phenolic plate and extruded board, such as raw materials for analysis, I believe you for the difference between the two models have a certain understanding.
