In terms of railway vehicles, Yadina melamine foam excellent acoustic characteristics, fire prevention security features to it can be in the car wall and roof support and pressure layer of decorative interior padding aspects play a role. In the application of the side wall and ceiling, the low heat conductivity of Yadina miamine foam can be conductive to show the performance of high efficiency insulation. For example, the operating costs of air conditioning vehicles can be greatly reduced. Because the Yadina mylamine foam has a lighter weight than other thermal insulation materials, it also has a great effect on energy efficiency in the transportation service industry. In addition, the weight of the car wall and the roof of the car reduces the weight of the vehicle, thus increasing the safety of the vehicle through the detour. This point is especially important for narrow track track. Yadina self-developed and produced melamine foam can be combined with PVC film, wool felt, non-woven fabric, PU board and other materials. For high-speed rail, light rail, subway and other rail transit industries. The Yadina mylamine foam can be used in the interior wall, roof, seat, side wall heat insulation, floor and the surrounding engine of equipment cabin, air duct, door, carriage. Yadina independently developed the lightweight properties of melamine foam (6-12kg/m cubed), which reduces the weight of the vehicle, improves the safety of turning and reduces energy consumption. At present, the south car north car group has used melamine foam as the insulation material. Yadina's independent development and production of micamine-soaked soundproof insulation is outstanding, and the comprehensive muting coefficient NRC=0.95 is the highest absorption coefficient of the existing foam materials. With the characteristics of its b1-level flame retardant, no flame retardant can be used to meet the flame retardant standard of national automobile parts.
