The present invention discloses a photo-crosslinked rubber composition and application thereof. The rubber composition comprises a rubber matrix and an initiator. Based on 100 parts by weight of the rubber matrix, the rubber matrix comprises a branched polyethylene with a content represented as A, in which 0<A≤100, and an ethylene-propylene rubber with a content represented as B, in which 0≤B<100; and the initiator accounts for 0.1-10 parts, and the initiator includes at least one of a cationic photoinitiator and a free radical photoinitiator. In the rubber composition, the ethylene-propylene rubber is partially or completely replaced by the branched polyethylene. The rubber composition can be used for rubber product crosslinked by ultraviolet light, including wire, cable, film, glove, condom, and medical catheter, which achieves excellent elasticity, electrical insulation property, aging resistance and ozone resistance, and also has good mechanical strength.
