What are the latest fire rating of the heat preservation material

What are the latest fire rating of the heat preservation material

Heat preservation material fire rating grade A is no ignition point have effect of heat preservation material, refuse burning materials. Rock wool board such heat insulation materials are widely used as heat pipe, equipment and other industrial pipeline equipment and industrial building heat preservation heat insulation material and the industrial and civil building palisade structure heat preservation, heat insulation, sound absorption materials.

Insulation fire rating B1 level is flame retardant insulation material, the phenolic board is set according to the fire resistance of the material, in addition, the materials are divided into different parts of the difference! Combustion performance: rock wool board price means material and (or) products in the fire burning all physical and/or chemical change, also is the fire response characteristics.

Heat preservation material fire rating B2 is combustible insulation materials also known as flame retardant materials, more for organic heat preservation material, adding the right amount of flame retardants. This kind of heat preservation material will release a large number of harmful gas in the combustion process.

Insulation fire rating level B3 is flammable insulation materials, wall rock wool board this rare thermal insulation material for polystyrene foam gives priority to material, because this kind of material easy to burn, in 2004, has been eliminated.
