Abstract
An elevator load bearing assembly () includes a jacket () having different portions comprising different polymer compositions. In a disclosed example, a plurality of tension members () are at least partially surrounded by a first portion () comprising a first polymer composition. A second portion () establishes at least one exterior surface () of the jacket () and comprises a second polymer composition. In one example, a surface-modifying agent is added to alter the composition of at least a portion of the jacket (). In another example, co-extrusion techniques using different polymer compositions establish different portions of the jacket ().
