ABSTRACT:
A surgical glove and method for making same is disclosed comprised of a polymeric matrix with at least one compact layer of very small particulate characterized by a very high hardness disposed therein. The disclosed glove and method is cost effective, easily adapted to present manufacturing methods, and provides a surgical glove which demonstrates a high resistance to cuts and punctures while maintaining a high level of elasticity and touch. The proposed particulate is one of a series of powders such as silicon carbide, carborundum, or diamond dust having a mean particle size of between 1-85 microns and a preferred particle size of between 5-8 microns, which can be applied to a curing elastic glove via spray or pre-mixing the particulate in the molten polymeric matrix prior to forming. The estimated thickness of the finished glove is approximately 2-7 millimeters, although greater thicknesses can be achieved by repeated processing at a cost of superior tactility but without loss of elasticity. More protection can be achieved by generating multiple layers of particulate sandwiched between layers of the polymer matrix.
