Phenolic insulation board level
phenolic insulation board is burning level B1 or grade A, believes that many construction companies buyers are concerned, burning level is A measure of insulation flame retardant performance data, C level is poorer, class A, class B in the middle. Bo hui insulating material and today you talk about phenolic insulation plate burning level related topics, in fact, the same level of combustion flame retardant performance is also different, such as tens of thousands and millions of cars are cars can run 120 km are qualified, but safety must be different.
phenolic insulation board
bare plate burning level:
bare plate burning phenolic insulation board level as the B1 level, is a class B level of inspection standard is higher, relative to the same kind of insulating material though is the B1 level, but the quality difference, such as instant B1 of polystyrene in fire and combustion with B1 level for phenolic insulation board level, but no obvious shrinkage carbide occur only under fire, more have not dripping, visible is the same level of insulation material quality differs a lot, each user when the choice must be treated with caution.
grade A phenolic insulation board
composite plate burning level:
composite phenolic insulation plate burning of grade A level, it is A bare plate phenolic insulation board in the smear adhesive mortar and pressure cloth of the grid technology, and air conditioning phenolic insulation board finish process basically the same, just A operation on buildings, another phenolic insulation board manufacturer in operation. Composite products can reach A level because phenolic foam itself close to the flame retardant grade A level, outside daub A layer of inorganic materials to make up for this deficiency also, so become A grade insulating material is not surprising, of course, is not only A kind of composite products, enhance the tensile, such as composite grid cloth composite aluminum foil to enhance the thermal performance, enhance the bonding performance of composite cement mortar paper and so on.
that is to introduce the relevant contents of phenolic insulation plate burning level, hope to help you, if you need this product, single ( Aluminum foil) Caigang phenolic plate please select city bo hui, my factory production equipment advanced, timely service, wholesale prices low, sample free of charge!
