The difference between phenolic composite insulation board and EPS insulation board
the article takeaway:
the difference between phenolic composite insulation board and EPS insulation board for all the year round in the insulation material of seasoning for people who do not have what, almost as easy one plus one equals two, for personnel entering the industry is a confused, let bo hui phenolic insulation board manufacturer to show you know the difference between phenolic composite insulation board and EPS insulation board, hope will be helpful to you.
phenolic composite insulation board picture
appearance and density difference:
phenolic composite insulation board core material composed of phenolic resin foam phenolic insulation board, appearance is light yellow appearance is exquisite, feel like tiny powder together in particular, the density of 40 kg to 70 kg heavier feel; EPS insulation board by polystyrene foam into even smaller particles in suction box thermosetting, finished product apparent white particles adhesion together one by one, the density of 5 kg to 25 kg feel lighter.
insulation performance difference:
phenolic composite insulation board coefficient of thermal conductivity of 0. 034w/( m。 k) EPS insulation board, coefficient of thermal conductivity of 0. 033w/( m。 k) 。 These two kinds of products on the insulation performance had no obvious difference, belong to the organic insulation material. Organic insulation insulation performance is good, can't rival with inorganic fireproof insulation flame retardant performance, because inorganic insulation material belong to products, such as rock, but inorganic material insulation performance than organic materials, such as rock wool insulation board heat conduction coefficient of 0. 046w/( m。 k) Insulation board, foam cement thermal conductivity coefficient of 0. 06w/( m。 k) 。
fireproof performance difference:
although phenolic composite insulation board and EPS insulation board belong to B1 level, but very big gap between the flame retardant! Phenolic composite insulation board without adding flame retardants, finished with a blowtorch tools such as combustion products, will find that in addition to air parts produced carbide, other parts of the safe, no embers, softening, no drip, no deformation; EPS insulation board not join flame retardant materials do not have flame retardant performance, in case of fire is extremely flammable, after adding flame retardants can achieve B1 level but encounters fire contraction, drop quickly, a piece of EPS insulation board under the effect of flame soon melted into a small piece of curing.
the price difference:
phenolic compound phenolic insulation board insulation board core material density 40 kg 320 yuan a kilogram, 30 yuan per increase 5 kg, density can be 70 kg; Density of EPS insulation board for air conditioning 18 kg to 20 kg, 14 yuan per kilogram. These two kinds of material are all changing as the raw material price change, users need to grasp the instant price in time.
that is to introduce about the difference between phenolic composite insulation board and EPS insulation 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!
