Abstract
An elastomeric compound comprises 20-80 parts per hundred cross-linkable materials of liquid elastomer. The liquid elastomer has a complex dynamic viscosity less than 5 McP (5,000 N*s/m2) at a temperature between 20° C. and the maximum flow temperature TF, and the elastomeric compound the elastomeric material has a complex dynamic viscosity of less than 5 McP (5,000 N*s/m2) for at least 2 minutes at a maximum flow temperature TF.
Claims20
A cured elastomeric compound, the cured elastomeric compound comprising, prior to cure, 20-80 parts per hundred of cross-linkable material (phcm) of a liquid elastomer and a cross-linkable functionalized polyethylene, wherein the elastomeric material has a complex dynamic viscosity of less than 5 McP (5,000 N*s/m2) for at least 2 minutes at a maximum flow temperature TF prior to cure.
A cured elastomeric compound comprising, prior to cure, 20-80 parts per hundred of cross-linkable material (phcm) of a liquid elastomer and a cross-linkable functionalized polyethylene, wherein the liquid polymer is selected from the group consisting of polybutadiene rubber, nitrile rubber, hydrogenated nitrile rubber, styrene-butadiene rubber, neoprene rubber, butyl rubber, polyisoprene rubber, and carboxylated nitrile rubber, and wherein the elastomeric material has a complex dynamic viscosity of less than 5 McP (5,000 N*s/m2)for at least 2 minutes at a maximum flow temperature TF prior to cure.
A cured elastomeric compound consisting of, prior to cure, 20-80 parts per hundred of cross-linkable material (phcm) of a liquid elastomer and a cross-linkable functionalized polyetheylene, wherein the liquid polymer is selected from the group consisting of polybutadiene rubber, nitrile rubber, hydrogenated nitrile rubber, styrene-butadiene rubber, neoprene rubber, butyl rubber, polyisoprene rubber, and carboxylated nitrile rubber, and wherein the elastomeric material has a complex dynamic viscosity of less than 5 McP (5,000 N*s/m2) for at least 2 minutes at a maximum flow temperature TF prior to cure.
