Cpe based welding hose

Abstract

A hose includes an inner tube containing a blend of chlorinated polyethylene (CPE) with ethylene propylene diene monomer rubber (EPDM), from 5 phr to 15 phr of a branched plasticizer, from 10 phr to 30 phr carbon black, from 30 phr to 60 phr mineral filling, and a peroxide curing agent. The hose defines an inner conduit. A reinforcement layer is disposed outwardly adjacent the inner tube, and an outer cover disposed outwardly adjacent the reinforcement layer. Upon and after curing, the inner tube at least meets methyl borate resistance, acetone resistance and pentane resistance requirements of Australian Standard AS1335. In some aspects, after curing the inner tube exceeds the methyl borate resistance, acetone resistance and pentane resistance requirements of the Australian Standard AS1335. Also, after curing, the hose at least meets flame resistance requirements of the Australian Standard AS1335.
