SOLUTION

D series polyimide foam products in the field of rail transit have the high and low temperature resistance performance (from-260 ℃ to 350 ℃, long-term service temperature 300℃) 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 cold resistance that other thermal insulation and sound absorption materials do not have. They can be used for cold protection of the whole vehicle.

Application:

The first battleship USN LCAC (landing hovercraft);

After 15 years of service, the performance of the foam material still meets the requirements;

Navy CG-47 escort missile cruiser,

Each ship can reduce weight by 50 tons;

with ultra-low smoke generation, almost no toxic gases or smoke release, bad weather resistance, acid and alkali resistance, long service life, and no water absorption failure.
