Abstract
A handrail includes a carcass, a stretch inhibitor arranged within the carcass, a cover bonded to the carcass, and a sliding layer secured to the carcass. At a central width axis of the handrail, a face height between an upper exterior surface of the cover and a bottom surface of the sliding layer may be less than about 8.0 mm. The carcass may be formed of a first thermoplastic material, the cover may be formed of a second thermoplastic material, and the first thermoplastic material may be harder than the second thermoplastic material. The first thermoplastic material may have a modulus at 100% elongation of between 10 and 16 MPa, and may have a hardness of between 93 and 96 Shore A.
