In a handrail including a carcass, a stretch inhibitor within the carcass, and a sliding layer bonded to the carcass, at least a portion of the carcass has a gas phase dispersed in a solid polymer matrix. The gas phase can reduce a density of the carcass by at least 5% or 10%, or about 15%, as compared to a density of the polymer matrix. The carcass can have a generally uniform distribution of gas bubbles in the polymer matrix, which can define a generally closed cell structure in the polymer matrix. The gas phase can be formed of particles of a syntactic foam dispersed in the polymer matrix. The handrail can further include a cover. The carcass and the cover can be formed of thermoplastic materials, and the cover can represent between 10 and 30% of the overall TPU required for the handrail.
