Abstract
Hoses include an inner tube, a reinforcement layer disposed outwardly from the inner tube, and a cover layer disposed outwardly from the reinforcement layer, where the cover layer and/or the inner tube includes a cured composition having a sustainable content and formed from a mixture including EPDM/EPR sustainable polymer and a sulfur or peroxide based curing system. In some cases, the EPDM/EPR sustainable polymer has ethylene monomer derived from one or more renewable sources, such as, ethylene monomer derived from sugar cane. The mixture may further include one or more of recovered carbon black and sustainable oils from renewable sources. The hose embodiments may also include the reinforcement layer formed of fibers from sustainable material. The hose may contain the sustainable content in an amount of up to 75% by weight based upon total hose weight, or even greater than 25% by weight based upon total hose weight.
