PI foam

天津时时彩走势图感觉 www.vpmtsz.com.cn

Polyimide foam (PI) refers to the material with imide in the macromolecular chain. It has comprehensive performances, such as inherent flame retardant, low smoke density, non poisonous, wide range of tolerable temperature (-269℃-300℃), low heat conductivity coefficient, easy for processing and installation, etc. It can serve normally over long periods of time in extreme conditions of superhigh temperature, ultralow temperature,intense salt mist, noise,corrosion and radiation.
PI is primarily used in ship cabins,pipeline heat preservation, sandwich layers in airplanes, thermal and heat insulation in aerospace crafts
