ABSTRACT:
An asphaltic isocyanurate foam useful in roofing applications. The foam is made from asphalt having a penetration range of between approximately 5-25, a softening point of between approximately 120.degree. F. and 200.degree. F., and an asphaltene content of no more than about 30%. This asphalt is liquified and mixed with a mixture of polyols such as Voranol 270, Multranol 9138, and castor oil. Other chemicals, such as a surfactant, a viscosity reducer, and a flame retardant can also be included in this mixture. The mixture is then brought to a temperature of between approximately 140.degree. F. and 220.degree. F., mixed with water and a polyisocyanate in a molar ratio of polyisocyanate:polyol of between about 2.0:1 and about 2.5:1 and reacted to form an asphaltic isocyanurate foam.
