TZ02 noise insulation material is composed MONIFLEX, high performance insulation cotton and rubber insulation material that is TZ02-A, TZ02-B and TZ02-C composite made of "sandwich" material. TZ02 set in one of the advantages of the three materials, and each of the constituent materials alternate each other long, performance is greater than the sum of the three materials performance, heat insulation effect is significantly enhanced. MONIFLEX cotton insulation and high-performance composite reached double insulation effect, and the noise after this two layers of absorbent filter rubber insulation board and then encounter a barrier, therefore, also aim to achieve effective noise reduction; MONIFLEX drop in insulation noise at the same time, can also be due to condensation water caused by temperature differences inside and outside the car smoothly export, not only reduces the weight of the body, but also extend the life of the material. This material has now been applied to ALSTOM 200Km / h EMU, 380 railroad cars and other cold items.
