Abstract:
A composition and method for making extruded polystyrene (XPS) foam is provided. The composition includes carbon dioxide as a major blowing agent to achieve an XPS foam having an improved thermal insulation performance.

Claim (Index 14):
A method of manufacturing a foamed insulation product, the method comprising:\n introducing a polymeric composition comprising polystyrene into a screw extruder to form a polymer melt; injecting a blowing agent composition into the polymer melt to form a foamable polymeric material, the blowing agent composition comprising at least 50 molar % carbon dioxide and at least one co-blowing agent selected from the group consisting of hydrofluorocarbons, HFO-1234ze, HFO-1336mzz, and combinations thereof; introducing at least one infrared attenuating agent into the polymeric melt; and extruding the foamable polymeric material through a die under a processing pressure of from 800 to 1200 psi into a region of reduced pressure to produce the foamed insulation product.
