Phenolic flame retardant high temperature insulation board poisonous
there's a phenolic board insulation board material called phenolic foam material, non-flammable, this material has good heat insulation and insulation, so generally used the material to produce phenolic flame retardant insulation board, use this kind of material made of composite flame retardant ability of phenolic insulation board is currently widely used polystyrene insulation board made of material such as, far less by general phenolic insulation board thickness is 25 mm thick fire prevention performance is very strong, even through 1700 ℃ flame long time continuous injection of 10 minutes, the surface will not be burning through, but merely the surface by carbonation.
modified phenolic fire insulation board will not catch fire, can't send out smoke and poisonous gases, so under the condition of high temperature phenolic flame retardant insulation board is non-toxic, so it is most used in workshop, cold storage, workshop need to fire insulation, building and so on. It was also because pf flame retardant insulation board prominent advantages is the fire prevention and insulation, so, now is widely used in air conditioning insulation system.
as some polystyrene material such as insulation materials, after combustion will produce a lot of smoke and toxic gases, can cause great harm to human body, and even life threatening, and at the same time, it's more difficult will increase. Phenolic insulation board and our a2 level meet fire will not burn, the fire resistance is very strong, to resist flame burning one hour will not be burning through, but also won't produce drip thing won't curl like burning some plastic products, etc.
our phenolic flame retardant insulation board can also be corrosion resistant, not afraid of strong acid and alkali substances, not afraid of the long exposure in the sun, its weight is light, the construction is very simple, quick, can well improve the work efficiency. And it is environmental protection product, there are no harm to the environment and human body, therefore phenolic flame retardant insulation board at high temperature is non-toxic, oh.
