ELEVATOR LOAD BEARING ASSEMBLY HAVING A JACKET WITH MULTIPLE POLYMER COMPOSITIONS
摘要
An elevator load bearing assembly (30) includes a jacket (34) having different portions comprising different polymer compositions. In a disclosed example, a plurality of tension members (32) are at least partially surrounded by a first portion (36) comprising a first polymer composition. A second portion (38) establishes at least one exterior surface (40) of the jacket (34) 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 (34). In another example, co-extrusion techniques using different polymer compositions establish different portions of the jacket (34).
