High-performance thermal and sound insulation material TZ02 ("sandwich" material)

Thermal and sound insulation materials are sandwich materials composed of high-performance thermal insulation cotton and rubber and plastic sound insulation materials. It combines the advantages of three materials into one, and each component material grows with each other. Its performance is greater than the sum of the three materials' properties, and the heat and sound insulation effect is significantly enhanced. It is compounded with high-performance thermal insulation cotton to achieve a double insulation effect, and the noise is absorbed and filtered by these two layers of materials and then encounters the rubber-plastic sound insulation board barrier. Therefore, it achieves the purpose of effective noise reduction while maintaining insulation and noise reduction. , it can also smoothly discharge the condensed water caused by the temperature difference between the inside and outside of the car, which not only reduces the weight of the car body, but also extends the service life of the material.
This material has now been used in railway projects such as EMUs and high-cold trains.
