Abstract:
Hoses include a tube, a reinforcement layer disposed outwardly from the tube, and a cover layer disposed outwardly from the reinforcement layer. The cover layer may be based on a first elastomeric blend of a first chlorinated polyethylene and chlorosulphonated polyethylene, a first flame-resistant composition, and a peroxide/sulfur curing system. The tube may be based upon a second elastomeric blend of a second chlorinated polyethylene and ethylene vinyl acetate rubber, a second flame-resistant composition, and a peroxide curing system. The first flame-resistant package and the second flame-resistant package includes one or more ingredients selected from the group consisting of antimony oxide, zinc molybdate/magnesium silicate complex, magnesium aluminum hydroxy carbonate, and aluminum trihydroxide. In some aspects, the hoses meet the testing performance requirements of EN 45545-2, HL2/R22 category standard, and EN854 type 2TE standard.
