目前,客车上装用的高压聚乙烯、聚苯乙烯原材料紧张,供货偏紧,价格又成倍上涨。玻璃棉制品是一种更好的新型保温隔热材料,还有不燃、吸声性能,且料源充足,经济耐用,发运便利。在客车上应用既可弥补高压聚乙烯、聚苯乙烯的供料不足,又可以降低造车成本。在电力、内燃机车上也有 At present, the passenger car with high pressure polyethylene, polystyrene raw materials tight, tight supply, the price has doubled. Glass wool products is a better new thermal insulation materials, as well as non-flammable, sound-absorbing properties, and adequate materials, economic and durable, easy to ship. Application in the bus can make up for high-pressure polyethylene, polystyrene insufficient supply, but also can reduce the cost of making cars. There are also on electric power, diesel locomotives
