Abstract: It has been demonstrated that it is possible to lower the density of rigid sulfur foam to as low as 10 lb/ft^3 in continuous pressurized process equipment and as low as 6 lb/ft^3 in laboratory glassware at atmospheric pressure. Based on past experience, each reduction of foam density becomes progressively more difficult to achieve. With further research the densities might be further reduced, lowering the unit volume cost of the material and improving the thermal conductivity of the foam. The attractive features of the foam include stress-strain characteristics which should allow use in a variety of structural applications; low thermal conductivity, making it a good thermal insulation material; low moisture absorption; low water vapor permeation; low cost; insensitivity to ambient temperature conditions but favored by low temperatures; and the capability of being produced at a remote field site.
