Rail transit D series foam products

Product advantages

The D series polyimide foam products produced by our company in the rail transit field provide a solution to the heat insulation and noise reduction system with light weight, high flame retardancy, ultra-low smoke generation and fiber free. Especially suitable for damp, high temperature, or restricted use of loose fibers.

D series polyimide foam products in rail transit field can meet the requirements of U S. FRA and FTA (Docket90-A) proposals to ensure a high evacuation rate in case of fire.

D series polyimide foam products in rail transit field have the high and low temperature resistance performance (-260 ° C-350 ° C), long-term service temperature 300 ° C that all thermal insulation and sound absorption materials on the market can not achieve. They not only have excellent flame retardancy than most thermal insulation and sound absorption materials, but also have the cold resistance that other thermal insulation and sound absorption materials do not have. They can be used to protect the whole vehicle from cold.

D series polyimide foam products in the field of rail transit have the lightness that other heat insulation and sound absorption materials cannot have, meet the requirements of train lightness, almost have no toxic smell, and ensure the comfort and environmental protection of the carriage. Compared to other materials, it also has better hydrophobicity, better resilience, no dust, and no slag falling.

Technical parameters

Used in rail trains and carriages instead of glass wool, weight reduction of 20%, replacing rock wool, weight reduction of 84%

It can reduce noise by 90% when used in rail trains and carriages instead of glass wool, polyurethane foam, carbon fiber and rock wool
