For rail vehicles, the excellent sound insulation, safe fire resistance and lightweight properties of Joylenge™ melamine foam make it the best choice for the rear door and roof system. When used in the car wall and ceiling, the high thermal insulation caused by the low thermal conductivity of the material becomes a major advantage. In this case, the operating costs of using air conditioners in the cabin will be greatly reduced. Compared to other insulation materials, Joylenge™ melamine foam itself greatly improves the energy efficiency of transportation services. At the same time, as the weight of the car wall and the ceiling is reduced, the center of gravity of the car body moves down, and the safety of the car body is ensured when the vehicle passes the curved track. This is especially important for vehicles that use narrow gauges such as subway trains and urban light rail trains.
China’s imported cars from Germany, Canada, France and Japan all use Joylenge™ melamine foam, which is used in the air conditioning system of trains, including air conditioning systems. The sound insulation of the motor and fan is used for the sound insulation of the air conditioning duct. Affected by the world’s leading rail vehicle design, self-designed rail vehicles in China gradually began to use Joylenge ™ melamine foam.
