    Abstract: An elevator rope of the present invention includes: a rope main body; and a covering resin layer that covers the periphery of the rope main body, the covering resin layer obtained by cross-linking a molded product of a composition comprising a thermoplastic polyurethane elastomer and a vinyl compound having two or more vinyl groups per molecule or a molded product of a thermoplastic polyurethane elastomer formed by using a polyol having a vinyl group for each molecule. In order to further stabilize the friction coefficient, inorganic fillers such as talc, a glass fiber and titanium oxide may be further mixed in the composition. The elevator rope of the present invention has a stable friction coefficient that does not depend on temperature or sliding velocity.

    Abstract: An elevator rope of the present invention includes: a rope main body; and a covering resin layer that covers the periphery of the rope main body and comprises a molded product of a composition for forming the covering resin layer, wherein the composition is produced by mixing a thermoplastic polyurethane elastomer, a thermoplastic resin other than the thermoplastic polyurethane elastomer and an isocyanate compound having two or more isocyanate groups per molecule. Preferably, a rope main body impregnated with an impregnating solution comprising a hydroxy compound having two or more hydroxy groups per molecule and an isocyanate compound having two or more isocyanate groups per molecule and having a lower viscosity than a melt viscosity of the composition for forming the covering resin layer is used as the rope main body. The elevator rope of the present invention has a stable friction coefficient that does not depend on temperature or sliding velocity.
