Shanghai, China – BASF is supplying a low-VOC water-blown PU spray foam insulation system for use in a new fleet of buses for the Chinese market.
The foam system, Elastoflex CE3651/108, was chosen because it gives better interior air quality than competing formulations, BASF said. The product has a lower density than competing alternatives, is easy to process and fast to apply.
‘This is the first time that BASF has developed a low odour spray foam system base on FR technology, which meets stringent FR requirements,’ said Desomond Long, BASF’s vice president for transportation performance materials in Asia Pacific.
The material has a limiting Oxygen Index >28, and so meets Chinese standard JTT1095-2016 for interior and insulation parts used on China’s buses. It is being sprayed on the ceilings of the buses to thermally insulate the roofs, and to cut the amount of noise inside the bus.
