欧洲铁路基建公司Edilon Sedra近期和亨斯迈公司展开合作,旨在开发一种可减少城市交通网络噪音污染的聚氨酯泡沫。据亨斯迈称,此产品是MDI基聚氨酯泡沫,可置于铁轨间的弹性垫中,这种聚氨酯泡沫可帮助分散列车运行时带来的各种压力和震动力,从而减少火车经过时巨大的隆隆声干扰 Edilon Sedra, a European railway infrastructure company, recently partnered with Huntsman to develop a polyurethane foam that reduces noise pollution in urban transport networks. According to Huntsman, the MDI-based polyurethane foam, which can be placed in elastic pads between rails, can help disperse all stresses and vibrations caused by the train’s operation, thus reducing the risk of trains passing by The rumbling noise
