Elastometric articles

摘要

A method of manufacturing a thin-walled polyurethane article includes dipping a shaped former into a coagulant solution and subsequently dipping the shaped former into an aqueous-phase polyurethane/plasticizer dispersion wherein the unplasticized polyurethane has a mean particle size of between about 0.5 mu m and 1.0 mu m and wherein the plasticizer causes the polyurethane particles to swell until they have a mean particle size of between about 1.5 mu m and 3.0 mu m. Articles so produced have a thickness of between 0.03mm to 1.0mm, a tensile strength of between 17 MPa and 60 Mpa and an elongation at break of greater than 650%.
