FOAM INSULATION MADE WITH EXPANDABLE MICROSPHERES AND METHODS |
摘要 |
A polyurethane and/or polyisocyanurate foam is made using expandable microspheres which encapsulate a primary blowing agent. By expanding during the foam making process, the microspheres function as a blowing agent. The foam preferably has at least 10% by weight expandable micro spheres which encapsulate a non-halogenated hydrocarbon chemical or a non-halogenated hydrocarbon chemical blend and less than 2% by weight of any non-encapsulate d blowing agents. |
