  • Phenolic foam composites and process for making them
    Patent number: 4501794
    Abstract: A continuous process for the production of a phenolic foam composite comprises bringing a preformed layer of flexible insulating material whose thermal conductivity is less than 0.10 W/m.degree. C. for example polystyrene foam into contact with a phenolic foam forming mixture and allowing the phenolic foam forming mixture to foam and set so as to form a layer of phenolic foam bonded to the layer of flexible insulating material.A second preformed layer of flexible insulating material whose thermal conductivity is also less than 0.10 W/m.degree. C. can be brought into contact with the phenolic foam forming mixture so as to form a sandwich structure with the layers of flexible insulating material bonded to opposite faces of the layer of phenolic foam. The effect of the layers of flexible insulating material is to decrease the variation in properties of the foam through its cross section.
