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.

About: DSM Engineering Plastics
DSM Engineering Plastics is a business group forming part of DSM's Performance Materials cluster. DSM EP is a global supplier of Stanyl PA46 and Akulon 6 and 66 polyamides, Arnitel TPE-E, Arnite PBT and PET polyesters, Xantar polycarbonate, Yparex extrudable adhesive resins, and Stamylan UH Ultra High Molecular Weight PE. These materials are used in technical components for electrical appliances, electronic equipment and cars, in barrier packaging films as well as in many mechanical and extrusion applications. The business group had annual sales of EUR 566 million in 2003. With Stanyl, it is the global market leader in high heat polyamides.Stanyl is a family of heat-resistant polyamides from DSM Engineering Plastics. Stanyl’s high crystallinity (70% versus 50% for conventional PA66) results in high heat distortion temperatures of 190C for unreinforced grades, up to 290C for reinforced. Stanyl grades are used in automotive clutch plates, charge air coolers, chain tensioners; electrical components including motor frames and end laminates, circuit breakers, controls and connectors; and home and power tool components, including heat shields and heat-resistant utensils.
