Fundamental Aspects of Thermal Conductivity Aging and Dimensional Stability of Rigid Polyurethane Foams

Source

One of the possible alternatives to eliminate the future use of CFC-11 as an essential blowing agent in rigid polyurethane foams, consists of a partial or complete replacement by carbon dioxide. The two major problems associated with the use of high levels of CO2 are first, a significant deterioration of thermal insulation capacity with time, and second, a potential loss of dimensional stability due to the rapid effusion of CO2. The paper gives an overview of the scope and limitations of this approach based on the results of extensive computational analysis and simulation.
