Abstract:
An elevator rope including 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 which 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; 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 has a stable friction coefficient that does not depend on temperature or sliding velocity.
