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.

Provided are a highly insulated rubber composition, a processing method therefor, and an application thereof. The rubber composition comprises a rubber matrix and compounding components. In parts by weight, every 100 parts of said rubber matrix comprise: 50-95 parts of a chlorinated (and/or chlorosulfonated) polyethylene rubber, 5-50 parts of a highly branched polyethylene, and 0-30 parts of an ethylene propylene rubber; and, the branching degree of the highly branched polyethylene is not lower than 50 branches/1000 carbon atoms. The compounding components contain a vulcanization system. The rubber composition improves the electrical insulation performance of the chlorinated (and/or chlorosulfonated) polyethylene rubber, so that the rubber composition is more suitable for the applications with high requirements for electrical insulation.

Disclosed are an aging-resistant rubber composition and a processing method therefor and use thereof. The rubber composition includes a rubber matrix and compounding components, and in parts by weight, every 100 parts of said rubber matrix comprise 50-99 parts of a halogenated butyl rubber, 0-50 parts of a highly branched polyethylene P1, and 0-50 parts of P2 obtained by the polarization modification of said highly branched polyethylene P1, and the sum of P1 and P2 in parts by weight is 1-50 parts; and said compounding components comprise a vulcanization system. The rubber composition improves the heat aging resistance of the halogenated butyl rubber, making it more suitable for high temperature environments, and also improves the properties of the halogenated butyl rubber which are related to the halogen content, such as the adhesiveness, oil resistance, flame retardancy and the like, by adjusting the extent of halogenation of the highly branched polyethylene which is employed in combination, thereby overcoming the limitation caused by the halogen content of the halogenated butyl rubber.
