Factory price customized density 10Kg/M3 sound insulation PI sponge, strong weather resistance polyimide marine foam

Flexible polyimide foam has inherent flame retardancy, it will not burn when exposed to an open flame, almost no smoke is
produced, and it does not produce any toxic substances, and it will be extinguished immediately after leaving the fire.

Because it is a closed-cell structure foam, it has good sound insulation and sound absorption effects

Compared with other traditional heat-insulating and sound-absorbing materials, our polyimide foam has good chemical stability and
weather resistance, does not degrade in extreme thermal environments, can maintain its original state after long-term use, and its
inherent basic properties There is no change. Because polyimide has high insulation, low thermal conductivity, and flame
retardancy, it can replace metals in many cases. Ceramics and high-temperature polymer materials make it widely used in high-tech
fields such as aerospace, electronic appliances, automobiles, machinery, ships, etc.

High and low temperature resistance, high flame retardant, radiation resistance, wave penetration, wave absorption, corrosion
resistance, long life, low slag drop rate, good resilience, heat insulation and sound insulation, easy processing, etc..

Polyimide foam has a strong radiation resistance. After absorbing 10000Gy dose, the size and appearance will not occur.
Significant changes can still maintain various excellent properties.

Polyimide has good high and low temperature resistance (- 260 ℃ ~ 300 ℃) due to its material characteristics and special
processing.
Because of these special properties,
It is widely used in aircraft, ship, automobile, medical and other industries
