  • Polyurethane/polyisocyanurate foam having improved adhesion properties
    Patent number: 8980422
    Abstract: A polyurethane/polyisocyanurate foam is obtainable from the reaction of A) a polyol component comprising A1) an aromatic polyester polyol, A2) a polyether polyol started on a carbohydrate polyol and A3) a polyether polyol started on ethylene glycol, wherein the total hydroxyl number of the polyol component A) is from ?150 mg KOH/g to ?300 mg KOH/g; with B) a polyisocyanate component, wherein the equivalent ratio of NCO groups to the sum of the hydrogen atoms reactive towards NCO groups is from ?110:100 to ?200:100. This foam has improved adhesion properties to facings and is suitable for the production of composite elements without requiring the use of an additional adhesion promoter.
