Kind Code:
A1
Abstract:
This rope for an elevator comprises: a rope main body; and a resin coating layer which covers the outer periphery of the rope main body and is formed by crosslinking a molded body of a composition that contains a thermoplastic polyurethane elastomer and a vinyl compound that has two or more vinyl groups in each molecule or by crosslinking a molded body of a thermoplastic polyurethane elastomer formed using a polyol that has a vinyl group in each molecule. For the purpose of further stabilizing the coefficient of friction, an inorganic filler such as talc, glass fibers and titanium oxide may be additionally mixed into the composition for molding. This rope for an elevator has a stable coefficient of friction that is independent of temperature or sliding rate.
