What role does dolomite play in rock wool products?
Pu hard foam layer can be firmly bonded with the base layer, the adhesive strength can exceed the tear strength of the foam itself, so Pu hard foam and the formation of the base layer, easy to delamination, to avoid the water along the interlayer
Polyurethane foam is a dense structure of the microporous foam, closed cell rate of 92% or more, with a smooth self-crust, is a good impervious material, in the construction of direct spraying molding technology, so Pu hard layer did not fight The overall formation of the entire impermeability of the seam, fundamentally put an end to the possibility of deepening the roof water from the seam
Polyurethane is a field foam molding, process equipment is simple, easy to operate, you can spray can also be poured, in any complex roof construction operations
Rock wool is a traditional insulation material, because it is inorganic materials, insulation performance is not very good
