ABSTRACT:
The present invention relates to an ablative fire resistant hydrophilic polyurea foam made from low molecular weight polyols capped with an isocyanate, with the polyol mixture including a fire retardant polyol that preferably includes carborane disilanol, with the fire retardant polyol containing the carborane disilanol imparting superior fire retardancy characteristics. The present invention also relates to a prepolymer for forming the polyurea foam and the present invention especially relates to the use of a carborane disilanol fire retardant polyol. The present invention also relates to a method for forming the polyurea foam and the prepolymer.
