PVC based medical gloves and formulations therefor
View Patent ↗A new formulation for making a polyvinyl chloride (PVC, usually referred as vinyl in glove industry) glove has been disclosed in this invention. The resulting glove shows the following superior barrier integrity characteristics by comparing with current vinyl gloves in the market: Much lower in use failure rate Improved puncture strength and tensile strength Better chemical resistance The invention provides formulations to make compounds and methods to make such gloves. The new formulations and procedures could be easily realized economically under common vinyl glove production lines. Depending on the desired applications, both powdered and powder free gloves could be produced in the same formula.
1. A glove, said glove made from polyvinyl chloride combined with a polyester plasticizer and a cross-linking agent, said cross-linking agent is 2,5-dimethyl-2, 5-di (t-butylperoxy)hexane.
2. A glove, said glove made from polyvinyl chloride combined with a nontoxic plasticizer and a cross-linking agent and a cross-linking agent, said cross-linking agent is 2,5-dimethyl-2, 5-di (t-butylperoxy) hexane.
3. The glove of claim 1 , wherein said polyester plasticizer is based on dicarboxylic acids and poly hydric alcohols.
4. The glove of claim 2 , wherein said polyester plasticizer is based on dicarboxylic acids and poly hydric alcohols.
