The difference between the phenolic insulation board and extruded board
the article takeaway:
phenolic insulation board with many users care about is the difference between extruded board, wall insulation material has a lot of, how the difference of their good cost performance is one of essential knowledge, let the phenolic insulation board manufacturer to take you under the comprehensive understanding of the difference between the phenolic insulation board and extruded board, let you in the field like a duck to water, order simple to follow.

fire retardant difference:
the relevant departments to vigorously advocate using class A insulation materials, inorganic materials, insulation performance is poorer level but the basic can achieve A2 and A1, organic insulation class is not A level of precedent, bare plate can only achieve B1 level, also don't flame retardant flame retardant insulation insulation in the strange phenomenon. Phenolic insulation board of flame retardant performance beyond A2 of B1 also short of asks, package made composite phenolic adhesive mortar board can achieve A2 level, bare plate carbide under high temperature fire in fire area, the remaining parts of the safe; Extruded board is also B1 level, but not the only lighter to constant lighting, you will find there are melting fireball drop, then rapid contraction, if using a blowtorch destructive lit a tragically, move the fire, most of the extruded plate manufacturers can put out a couple of seconds, also have a fire was extinguished, after all, after join material fire site average.

insulation performance difference:
insulation performance comparison, from the coefficient of thermal conductivity can see it more intuitive, the smaller the coefficient of thermal conductivity value represents the insulation insulation performance is better. The coefficient of thermal conductivity of phenolic insulation board is 0. 033w/( m。 k) , the coefficient of thermal conductivity of extruded board is 0. 032w/( m。 k) , the two insulation insulation performance close to, what kind of insulating material selected design units or feel different.
physical properties difference:
phenolic insulation plate appearance is light yellow plate insulation materials, to enhance with the increase of density of compressive strength, its density between 40 kg to 70 kg; Extruded board body is light yellow, blue wait for color according to user's love can make it, according to user demand for air conditioning use density about 35 kilograms, underground garage using density can be up to 50 kg. As they have in common specifications are 1200 x600 mm.
the price difference:
phenolic insulation plate calculation price according to the density, density of 40 kg 320 yuan 380 yuan per cubic and density of 50 kilograms of a cubic, density of 60 kg 440 yuan to 500 yuan per cubic, density of 70 kg of a cubic; Extruded plate is divided into price according to the flame retardant performance, ordinary not flame retardant, 240 yuan a cubic, 450 yuan a cubic of B2, B1 level according to the factory price difference is very big, 550 yuan to 650 yuan between, such as and trade-offs or many things.
is to introduce the above about the difference between the phenolic insulation board and extruded board related content, 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!
