Polyurethane foam and what are the difference between the phenolic foam
polyurethane foam and phenolic foam insulation materials building materials products, polyurethane foam and what are the difference between the phenolic foam, their common insulation performance is good, the advantages of the two products used for building air conditioning outer insulation, air conditioning, basement roof insulation, insulation equipment spray interlayer insulation, insulation, etc. , so as building insulation material what is the difference between them?
phenolic foam picture
all kinds of foam products:
and insulating foam is a lot of more phyletic, the related plastic products of lightweight insulation materials commonly are planning to this category, such as phenolic foam, polyurethane foam, high pressure polyethylene foam board, extruded foam board, rubber and plastic foam board, PE foam board and so on, their role is insulated. But purpose different some used as insulation wall some equipment insulation, let's see.
raw materials, bulk density is different:
polyurethane foam is black and white material mixed natural polyurethane foam, its density is used to plate can make 30 kg to 70 kg, used in tube and shell density is 200 kg; Phenolic foam is made from foam phenolic resin in foaming agent, its bulk density is generally between 40 kg to 80 kg, phenolic foam insulation board density in the great assembly line basic cannot support, can send form to mould making but it is mainly used for equipment insulation or roof insulation, the basic no for air conditioning.

coefficient of thermal conductivity, the price is different:
polyurethane foam thermal conductivity is only 0. 028w/( ㎡。 k) , insulation performance is good but the price is very high, such as the thickness of 2 cm a cubic polyurethane foam plate 1100 yuan, 750 yuan a cubic 5 cm thickness; Phenolic foam density of 40 kg per cubic metre of 320 yuan, 60 yuan per 10 kg cost; A relatively low price more than one times, its coefficient of thermal conductivity in 0. 03w/( ㎡。 k) Left and right sides, flame retardant performance is more than double of polyurethane foam, the foam insulation flame retardant performance among the best in the class.
the above is about polyurethane foam and to introduce the related contents of what are the difference between the phenolic foam, 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!
