  • This invention relates to thermal insulating foams for panel and pour-in-place foam applications and to compositions, methods and systems which use and/or are used to make such foams, and in particular to foams having one or more improved properties, including particularly improved certain dimensional stability properties, and to compositions, methods and systems for making and using same.
  • Polymeric or plastic foams in general have numerous and widely varying applications and can be formed from a wide variety of materials.
  • the material which forms the matrix, or solid portion, of the foam can be a thermoplastic or a thermosetting material, and each of such materials can be used and has been used in a wide variety of applications.
  • One such application is to provide thermal insulation.
  • One desirable property for thermal insulating applications is to provide the foam with a resistance to the flow of heat that is as high as possible. This property is frequently measured in terms of the thermal conductivity of the foam, and the resistance to the flow of heat generally increases as the thermal conductivity of the foam decreases.
  • blowing agent used for the formation of foam materials can have an impact on one or more properties of the foam that is produced. It has been noted, for example, that blowing agent composition which are pure single components have an advantage in that the make-up of the composition will not change during its application in the foaming process, and that this advantage is generally shared by blowing agents which are azeotropic or azeotrope-like mixtures of compositions.

  • the Robin patent teaches that using compositions which are not azeotropic or azeotrope- like could detrimentally affect processing or cause poor performance, and therefore teaches away from using this combination of components outside of the above-noted ranges.
