Abstract
An carboxylated nitrile-butadiene rubber latex formulation composed of a blend of a first acrylonitrile terpolymer and a second acrylonitrile terpolymer, wherein: the acrylonitrile content of the blended terpolymers is between 17 and 45% by weight, the methacrylic acid content of the blended terpolymers is less than 15% by weight, and the remaining balance of the terpolymers being butadiene. The invention also includes an elastomeric nitrile rubber article made from the formulation.
Claims7
A carboxylated nitrile-butadiene rubber latex formulation comprising a blend of a first acrylonitrile terpolymer and a second acrylonitrile terpolymer, wherein the first acrylonitrile terpolymer and the second acrylonitrile terpolymer are in a compositional ratio ranging from 60:40 to 40:60, wherein:
- the blend has an acrylonitrile content between 17 and 45% by weight, and
- the blend has a methacrylic acid content of less than 15% by weight,
- wherein a remaining balance of the blend is butadiene.
