Estimating the term…
A conveyor belt including a carry cover layer, a reinforcement layer which is situated below the carry cover layer, and a pulley cover layer which is situated below the reinforcement layer, where the reinforcement layer is comprised of steel cordage and rubber matrix, and wherein the rubber matrix includes zinc oxide in an amount greater than 5 phr and a cobalt derivative in an amount of 1 phr or greater. In some cases, the rubber matrix includes zinc oxide in an amount of 11 phr or greater, or even in an amount of 16 phr or greater. In some cases, the rubber matrix includes the cobalt derivative in an amount of 2 phr or greater, or even in an amount of from 3 phr to 4 phr. In some aspects, the rubber matrix is devoid of lead oxide.
A conveyor belt which is comprised of a carry cover layer, a reinforcement layer which is situated below the carry cover layer, and a pulley cover layer which is situated below the reinforcement layer, wherein the reinforcement layer is comprised of steel cordage and rubber matrix, and wherein the rubber matrix comprises zinc oxide in an amount greater than 5 phr and a cobalt derivative in an amount of 1 phr or greater.
A conveyor belt which is comprised of a carry cover layer, a reinforcement layer which is situated below the carry cover layer, and a pulley cover layer which is situated below the reinforcement layer, wherein the reinforcement layer is comprised of zinc coated steel cords and rubber matrix, and wherein the rubber matrix comprises zinc oxide in an amount greater than 5 phr and a cobalt derivative in an amount of 1 phr or greater.
A rubber article which is comprised of a reinforcement layer, wherein the reinforcement layer is comprised of steel cordage and rubber matrix, and wherein the rubber matrix comprises zinc oxide in an amount greater than 5 phr and a cobalt derivative in an amount of 1 phr or greater.
