Recently, the new EPM sound insulation mat developed by ZZSD Advanced Materials Technology Group was successfully tested on the 250 kilometers per hour Fuxing standard EMU of CRRC Tangshan Company. This is the first time that ZZSD sound insulation materials have been applied to Fuxing standard EMUs, and it also means that ZZSD sound insulation materials have made new breakthroughs in the rail transit market, laying the foundation for the subsequent development and application of this type of product.
With increasingly stringent environmental protection requirements for sound insulation materials at home and abroad, traditional PVC sound insulation materials have been unable to keep up with the requirements. The new EPM sound insulation material developed by ZZSD is not only environmentally friendly and odorless, but also has the characteristics of high density, high strength and high flexibility. It has obvious vibration and noise reduction effects. It is mainly used on the back of the floor and the lower part of the pantograph of the Fuxing standard EMU. Flat area and front of the car.
The rail vehicle interior market is the development direction of ZZSD in recent years. The successful trial installation of the new EPM sound insulation material is a recognition of the R&D and design capabilities of ZZSD acoustic products and also provides a strong guarantee for the promotion of subsequent new products.
