Cord and polymer jacket assembly having a flame retardant in the polymer jacket material

摘要

A load bearing assembly (26) for an elevator system (20), the load bearing assembly comprising:
at least one elongated tension member (32);
a jacket (34) in the form of coating covering at least some of the at least one tension member, wherein the jacket material comprises a mixture of
(a) a polymer material (64, 68); and
(b) a halogen-free melamine based intumescent flame retardant (62) comprising at least one of melamine-cyanurate, melamine-phosphate, melamine pyrophosphate or melamine polyphosphate. Also a corresponding method of making such a load bearing assembly (26) is disclosed.
