Melamine foam is a new type of melamine foam with high open porosity and three-dimensional grid structure. It has good sound absorption, flame retardancy, heat insulation, moisture and heat stability, hygienic safety and light weight. And good secondary processing performance. These characteristics make the product have broad prospects for the wall and roof support of rail vehicles as well as the decorative interior filling of laminated layers.
The strong thermal insulation properties of the melamine foam are a great advantage, which not only can effectively reduce the operating and operating costs of using air conditioners in air-conditioned passenger cars, but also greatly reduce the noise outside the cabin.
In addition, the melamine foam is lighter in weight, and the weight of the vehicle wall and the top of the vehicle is reduced, so that the center of gravity of the vehicle is lowered, thereby increasing the safety of the vehicle when passing the curved road. Melamine foam is particularly important for narrow-gauge railways in wall and ceiling applications.
Application
Melamine foam can be compounded with PVC film, felt, non-woven fabric, PU board and other materials, and used in rail transit industries such as high-speed rail, light rail and subway. Melamine foam is suitable for use in equipment cabins, air ducts, doors, interior walls of vehicles, roofs, seats, side wall insulation, flooring and engine peripherals. Melamine foam absorbent sponge has been widely used in rail vehicles.
Melamine foam advantage
1. Melamine foam is light (4-12kg/m3), which can reduce the weight of the whole vehicle and improve the safety of cornering (important for narrow-gauge track roads) and reduce energy consumption.
2. Melamine foam has good sound insulation effect, high sound absorption coefficient, and can meet the flame retardant standard of automobile parts without flame retardant. This can play a role in the rail vehicle wall and roof support as well as in the decorative interior trim of the laminate. It can be used in the side walls and ceiling of air-conditioned passenger cars, which can greatly reduce operating costs.
Now, CSR cars have begun to use melamine foam products with good sound absorption, flame retardancy and environmental protection. We can provide various specifications and dimensions of melamine foam, and is a supplier of car sound absorbing sponges and automotive thermal insulation sponges.
