摘要： 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.

摘要： 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.

摘要： A handrail has a thermoplastic body having a generally C-shaped cross section, a stretch inhibitor in the thermoplastic body above a T-shaped slot and a slider fabric layer. The handrail includes first and second end portions, each comprising a forward part extending from an end surface of the end portion and a rear part adjacent the forward part. A method of forming a joint can include: providing cuts to separate a top section of the thermoplastic body from a base section including shoulder portions; for each end portion, removing at least shoulder portions from the forward part thereof, to leave a central portion including a forward part at the slider fabric layer and a layer of thermoplastic; cutting the forward parts to a required shape; and assembling the first and second end portions together to form a spliced joint for moulding.
