The invention discloses an oil-proof high-low-temperature-resistant elastomer for an express elevator cable. The elastomer comprises raw materials of, by weight, 50 to 100 parts of high molecular weight HPVC, 25 to 60 parts of PVC, 5 to 20 parts of thermoplastic polyurethane, 1.5 to 10 parts of an environment-friendly heat stabilizer, 20 to 90 parts of a plasticizer, 1 to 10 parts of an antioxidant, 5 to 40 parts of filler, 1 to 10 parts of a lubricating agent, 8 to 40 parts of a flame retardant, 8 to 40 parts of flame retardant synergist and 1 to 20 parts of a polyvinyl chloride processing agent. According to the elastomer, the HPVC and the thermoplastic polyurethane are jointly mixed so that the defects that HPVC resin is poor in processing fluidity and the abrasion resistant performance can not meet the requirement of an elevator cable material can be effectively overcome, cold resistance and weather resistance of the material can be improved, and the elastomer has certain softness and fatigue resistance; the flame retardant is added, under the condition that the material is kept soft, flame retardance of the material can be improved, an oxygen index of the material is larger than 32, and the flame retardance is good.
