Sustainable rubber compound for power transmission belt

Abstract

An article such as a power transmission belt includes an elastomeric body and at least one reinforcement cord disposed in the elastomeric body. At least part of the elastomeric body is formed from a rubber compound including styrene butadiene rubber (SBR) sustainable polymer. The rubber compound may include additional sustainable materials, such as one or more of additional sustainable rubber, sustainable fiber, sustainable carbon black, sustainable plasticizers, or the like. The rubber compound may have an overall sustainable content of 50% or greater, or even greater than 65%, such as up to about 95% or more total sustainable content for the rubber compound. The article may include further sustainable material, such as sustainable fabrics and/or sustainable reinforcement cords. The overall article may have a total sustainable content of 50% or greater, or up to about 95% or more total sustainable content for the article.
