High-performance insulation cotton (TZ02-B) is 100% environmentally friendly products. Is high-performance insulation fiber insulation blankets by pressing, bonding and other processes made. Train body is designed for cold and research materials. The performance indicators have reached the train cold material standards. In addition to good heat insulation, sound insulation, fire-retardant performance it is one of the highlights, when burned, produces no toxic gas, no dripping, smoke density to meet the requirements, and has from the fire self-extinguishing characteristics. The cotton insulation insulation role in the play also play an effective role in acoustic noise. With the introduction of high-speed trains, high quality lightweight cotton insulation extremely beneficial to the body weight control, therefore, but also accelerated the pace of its breadth of applications. Compared with the traditional high-performance insulation cotton insulation materials (TZ02-B) has the following advantages: 100% recyclable; easy processing, can be made into various shapes according to different needs, construction safety and convenience; long life;??? ? will not rot, can withstand a variety of microorganisms, fungi, acids, salts and hydrocarbons corrosion;? any harmful substances, odorless, does not contain formaldehyde;? waterproof, breathable performance; extremely light weight of the material has been used now in ALSTOM 200Km / h moving on EMU, 380 railroad cars and other cold items.
