the article takeaway:


phenolic insulation plate and the difference between extruded board has been bothering you, what's the difference between the density and fireproof performance has been widely concerned. Please follow below Po hui insulation materials manufacturers understand the phenolic insulation board together and the difference between extruded board, hope for your help, more products please contact us for help.

material and appearance difference:


in phenolic foam foam phenolic insulation board, exterior grayish yellow to pale white fine powder surface curing condition, phenolic foam flame retardant performance is very high, extruded board raw material for styrene, it can be made into many kinds of products, including plastic extruded board material, polystyrene board, and other products, it is commonly blue, can adjust the color according to customer's requirements.

flame retardant performance:


phenolic insulation board and extruded board can be caught fire B1 level, but they are very big gap between the actual flame retardant performance. Phenolic insulation board makes carbide under high temperature fire, close the fire around there is no fire is of light and shade, phenolic board did not melt or deformation phenomenon, its fire prevention performance is very close to the A2 level; Extruded board flame retardant performance, although is also B1 level, but under high temperature and flame melt quickly, just use lighter sampling light often burst into flames and then go out for more than a few seconds, this is because the add of flame retardants and extruded board density is not the same as raw materials, is difficult to completely mixed evenly, and phenolic foam itself without adding flame retardants, itself is a very good flame retardant materials.


density price:


phenolic insulation board density can be made between 40 kg to 70 kg, phenolic plate density 40 kg price 320 yuan, 30 yuan per 5 kg growth; Extruded plate classification is more, ordinary plate density around 27 kg per cubic metre of 300 yuan. B2 board per cubic metre of 450 yuan. B1 extruded board requires 550 yuan a cube. And this is not to say extruded board, phenolic board price vary too much, it also has its own advantages, such as insulation and box pressure strength slightly higher than the phenolic board.


the above is about phenolic insulation board and to introduce the relevant contents of the difference between extruded board, 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!
