THINKING
What distinct advantages can new thermoplastic materials bring to the rail sector?
he transport sector’s design and manufacturing processes have long been trending towards requirements for
greater fuel efficiency, providing a luxury riding experience, and enhanced safety. As more mass equals more fuel consumption, utilising materials that reduce the overall weight of passenger buses, trains and aircrafts will in turn lead to decreased energy consumption, less brake and tyre wear, and lowered emissions. Thermoplastics offer the transport
sector focused material options that are simultaneously rigid, durable and lightweight, alongside a manufacturing process that enhances

design capability, lead time, and the look and feel of components. The rail industry in particular is harnessing these advantages by leveraging thermoplastics for interior applications such as wall and ceiling panels in passenger trains, subways and trams.
NEW THERMOPLASTICS One such example is the recently launched range of LNP Elcres FST copolymers from chemical specialist Sabic, which are designed specifically for rail interior wall panels. Fully compliant with the European railway standard for fire safety, the new specialty thermoplastic meets the key requirements of rail OEMs in regard
to durability and custom colourability. Specifically, the material offers high modulus for durability, moulded-in custom colour for paint elimination and branding, ultraviolet (UV) resistance to help minimise yellowing, and chemical resistance to facilitate cleaning removal without causing environmental stress cracking. According to Sabic, LNP Elcres FST
provides distinct advantages over stamped metal and thermoset resin alternatives, such as expanded design freedom and system cost reduction. Additional benefits include 20% less weight for easier maintenance as well as the potential for easier recyclability. “As travel rebounds, the rail industry
