Polyimide not only has excellent high-temperature resistance (350 ℃) but also excellent low-temperature resistance (-260 ℃). Its long-term use at a temperature of 300 ℃ has important application value in the field of deep space exploration.
Product advantages
Lightweight | Aerospace H series polyimide foam products are extremely light, which means saving fuel and increasing payload. Other thermal insulation materials may degrade under extreme high and low temperature conditions in a wide range of service temperatures, but aerospace H series polyimide foam products still maintain their original performance. Even at ultra-low temperature, aerospace H series polyimide foam products can still maintain their flexibility. |
Flame retardancy | With its inherent flame retardancy, aerospace H series polyimide foam products hardly produce smoke or toxic substances causing dysfunction when encountering open fire. |
Environment protection | Aerospace H series polyimide foam products do not need special processing technology. Halogens, heavy metals, formaldehyde or ozone depleting chemicals are not used in the production of aerospace H series polyimide foam products. |
Sound absorption/thermal insulation performance |
Aerospace H series polyimide foam products have excellent sound absorption performance and good thermal insulation performance. |
Weather resistance |
Compared with other commonly used heat insulation and sound absorption materials, aerospace H series polyimide foam products have better damage resistance. In the vibration environment or the extreme cold and hot environment where other thermal insulation and sound absorption materials may degrade, aerospace H series polyimide foam products still remain in their original state after a long time of use. Aerospace H series polyimide foam products also have good chemical stability, resistance to hydrocarbons, ethanol and dilute acids. |
