Product Name: Flexible Polyimide Foam

Item No.: SolverPI-Flexible Foam

 

Since 2010, based on the original technology and refer ourself to the international technical standard, SOLVER POLYIMIDE developed a new type of flexible PI foam integrated production line has been built,with1000MT annual output. With different needs,we can produce the PIfoam of density and intensity.The PIfoam has the characters of high and low heat resistence,High fire retardent,radiation resistence,wave-transparent,microwave absorpting,anti-corrosion,longlife,excellent comprehensive properties,the high rate of obturator,easy processing. It can be widely used in aviation, spaceflight, navigation, transportation, construction and so on.

This product has past the fire retardancy test in the Yuandong fire experiment center.And the result show that our material is in well accordance with the technique target of smoke density、toxicity test、low flame-spread combuston heat value in《International fire test program application rules》require.The room temperature emissions、high temperature split product、inhalation toxicity experiments on animals are in accordance with human bddy health standards after Non metallic material inspection center of People’s Liberation Army Navy detection.
