CA 2214770

This invention relates to insulating foams and to a process for producing the foams. Preferably, the foams are made from phenol formaldehyde resins. The blowing agents for making the foams include a film-forming coating material which coats the interior surfaces of the foam cells. The coated foams have better thermal conductivity.

La présente invention se rapporte à des mousses isolantes et à un procédé de fabrication des mousses. De préférence, les mousses sont fabriquées à partir de résines phénol-formaldéhyde. Les agents gonflants pour fabriquer les mousses comportent un matériau d'enduit filmogène qui enduit les surfaces internes des cellules de mousse. Les mousses enduites possèdent une meilleure conductivité thermique.
