Excellent integrated solution for rail interiors.

The most secure sound insulation material for railway

Melamine foam has a good acoustic effects in rail vehicles, and has the characteristics of heat preservation, fireproof and light weight. It is also widely used in the music room or indoor walls, ceilings for interior decoration, and can achieve a good sound-absorbing effect.

Foam Tech’s melamine foam has excellent noise reduction performance, thermal stability and lightweight and thermal insulation properties, and has the advantage of lighter weight compared to other materials with the same properties, thus it can improve the energy efficiency of rail trains. Therefore, Foam Tech’s melamine foam with the characteristics of reducing operating costs and improving the stability of the turn, it has obvious advantages in high-speed rail trains such as high-speed railway, subway.


The melamine  foam is usually used in the cab, passenger compartment, mezzanine, air-conditioning duct, side wall, floor and top of the train after compounding with aluminum foil material and self-adhesive backing. In some operating environments of high-speed rail, there is a large temperature difference between day and night, and it is filled around the high-speed rail. Flexi melamine foam for optimum acoustics and comfortable temperature for passengers. The materials provided by melamine foam manufacturer FoamTech  maintains acoustic performance and thermal insulation even in extremely harsh environments.
