Abstract: An illustrative method of making an elevator load bearing member having at least one elongated tension member at least partially covered by a jacket includes mixing a flame retardant with a polymer material. The flame retardant is selected from a group consisting of (i) a halogen-free melamine based intumescent comprising melamine cyanurate, melamine-phosphate, melamine pyrophosphate or melamine polyphosphate in an amount up to about 20% by weight of the thermoplastic polymer or (ii) a filled polymer having a nanoscale filler chemically bonded to a matrix phase. Applying the mixed flame retardant and polymer material to the tension member forms a jacket of a desired shape.

Abstract: An illustrative example method of making an elongated load bearing member includes providing a plurality of tension elements. A plurality of weave fibers are woven together with the tension elements to thereby establish a weave. A traction surface is established on at least one side of the load bearing member. The traction surface is defined by the weave fibers. Coating the weave fibers with a compressible coating provides an exterior surface texture defined at least in part by the weave fibers.
