Teijin Fibers Limited, the core company within Teijin Group's polyester fibers business, announced that its lightweight, high-performance ELK polyester cushion materials are being used in the new advanced "N700 Series" shinkansen bullet train.
ELK is a polyester elastic fibrous material that has found growing application as an alternative to traditional foamed polyurethane. Teijin Fibers' ELK is lightweight, air-permeable and recyclable, and exhibits significant elasticity and durability.
At a time when Japanese railway companies are seeking ways to deliver passenger trains that are lighter, more energy-efficient, and recyclable, demand is on the rise for materials with ELK's characteristics. In fact, 20% of the approximately 50,000 passenger cars operated by Japan Railways Group and private Japanese railway companies feature seats made of ELK. The ratio is highest for commuter trains operated in high-volume metropolitan areas.
The first N700 Series shinkansen entered service on July 1, 2007, featuring seat backrests made of ELK. All told, Teijin Fibers expects to supply materials for about 60,000 N700 Series seats. Teijin Chemicals Ltd., a specialty plastics company in the Teijin Group, is meanwhile supplying highly durable Panlite polycarbonate resin for N700 Series windows under a deal announced on June 28 this year.
Building on the momentum generated by its use in Japan's next-generation shinkansen, Teijin Fibers will attend an international exhibition for train interior materials being held this November in Koln, Germany for the purpose of introducing ELK to the European Union. The company also hopes to expand sales of ELK for application to the automobile, aircraft and furniture manufacturing industries.
