Dutch railways is using Xantar C CE 407, an unfilled blend of polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS) from DSM Engineering Plastics to replace train cladding made from polyester sheet.
The DSM material was chosen for its lower flammability (M1 classification) and extremely low generation of toxic smoke when burning (F2 classification) due to its use of bromine- and chlorine-free flame-retardant (FR) additives.
The Xantar C thermoplastic is more friendly to the environment and processor because, unlike polyester, the thermally stable blend can be economically and easily extruded into sheets and then vacuum-formed into cladding, even in combination with a co-extruded protective polyvinylidene fluoride (PVDF) top layer.
