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 exemplary assembly includes at least one elongated tension member. A jacket covers at least some of the tension member. The polymer jacket comprises a polymer material including a melamine based geometry stabilizer that facilitates maintaining the jacket material near the tension member if the assembly is subjected to a high temperature condition.
Abstract translation: 示例性组件包括至少一个细长张力构件。 护套至少覆盖一些张力构件。 聚合物护套包括聚合物材料，其包括基于三聚氰胺的几何稳定剂，如果组件经受高温条件，则有助于将护套材料保持在张紧构件附近。
