ABSTRACT:
A cellular synthetic medical cast is made using fabric strips and a dispenser unit containing blowing agent and a water-activatable polyurethane prepolymer under superatmospheric pressure. A trimerizing catalyst is infused in the prepolymer mass immediately before the composition is dispensed in a bead onto the fabric strip; and thereafter, mechanical compressive force is applied to the foam bead to dimension it, embed it in the fabric and regulate the degree of reticulation. The impregnated strips are wrapped to form the cast and contacted with moisture to produce rapid cure of the prepolymer.
