These liquid hydrofluorocarbon blends are from Solvay, one of our partners from Germany. Specifically, Solkane® 365 is the key component to form a range of promising blowing agent blends whereas Solkane®227 is a propellant for pharmaceutical aerosols. A blend of Solkane® 365/227 is used for firm PU foams for insulation purposes because of its low thermal conductivity and good compressive strength.
