WebFoam products are manufactured with chemical blowing agents that expand the plastic matrix before it solidifies. The type and amount of blowing agent used, as well as the processing conditions applied, determines the final density of the foam that is generated. WebThe overall performance of pentane blown rigid polyurethane foams in terms of insulation value and mechanical properties is demonstrated. The low vapor pressure of both normal-pentane and cyclopentane is shown to induce condensation effects. The consequences of condensation in terms of thermal conductivity and dimensional stability are discussed.
