Polyurethane Raw Materials for Foam Production in Rail Transportation

Comfort and Durability in Rail Transportation

Passenger seats in rail vehicles such as trains, metros, and trams accommodate different passengers throughout the day. Despite frequent and repeated use, these seats are expected to provide a comfortable seating experience while maintaining their shape over time. For seat manufacturers, selecting the right foam structure is essential to meeting these expectations. While foam flexibility and durability influence seating performance, fire safety requirements in passenger transportation also play an important role in material selection.

To address these needs, Kimpur has developed KIMflex® HR Foam Systems for seat manufacturers in the rail transportation industry. Designed for the production of molded flexible polyurethane foam components used in passenger seating, these polyurethane raw material systems combine comfort, long-term durability, and fire performance.

The high resilience of HR (High Resilience) foams allows the foam to recover its original shape after being compressed under load. Thanks to their resilience and dimensional stability, foams produced with KIMflex® HR Foam Systems help maintain seating comfort under repeated use. This enables manufacturers to develop seats that provide comfort during long journeys while withstanding the demands of intensive daily use.

In rail seating applications, achieving comfort and durability with a foam structure that meets fire safety requirements is equally important. KIMflex® HR Foam Systems meet the applicable heat release and smoke density requirements specified under EN 45545-2, offering low smoke generation and low toxic gas emissions. Their low volatile organic compound (VOC) emissions also contribute to maintaining indoor air quality during use.
