Abstract
A new formulation for producing nitrile gloves has been developed. The resulting glove shows following outstanding characteristics: stress at six minutes greater than 50% of its initial value; ultimate tensile strength and elongation well above ASTM requirements; and much lower modulus than almost all the nitrile gloves currently commercially available. The unique formulation is zinc oxide free and is vulcanized from 5 to 60 minutes at temperatures ranging from 300° F to 400° F.
