Abstract
This invention provides means to replace vulcanized natural rubber with non-allergenic synthetic rubbers in the manufacture of health care devices such as protective gloves, condoms, tourniquets and dental dams. The synthetic rubbers are latexes and aqueous polyurethane dispersions having very low glass transition temperatures and crosslinked by means other than sulfur vulcanization of double bonds.
