AbstractThe technology for manufacturing high thermal performance cellular plastic insulations such as polyurethane, polyisocyanurate, phenolics and extruded polystyrene uses gases with low thermal conductivity as captive blowing agents. The gas is captured in the closed cells of the material to achieve higher thermal resistance. But once in contact with the atmosphere, the thermal resistances of these materials gradually decrease. This phenomenon is called aging.
