Flexible Polyimide 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. Appearance requirements 1.1Surface:The surface should be smooth,the form hole be well-distributed. 2.2Qualty:Product quality and conditions should be consistent,clean,no impurities and defects affecting the processing or material properties. 1.3Color:The original color unless special provision. 1.4Toxicity:Avirulent,no harm to the skin long-term exposure. 1.5Odour:Odorlessness. 1.6Thickness:Based on the order,the error±5％ is permitted. The concentration of harmful gases does not exceed the requirements of GJB 11B provisions of the cabin air froup divided allowable concetration.The material of the median lethal concentration LC50≧50g/m3. According to the 2010FTP rules of Annex 1 second part2--The smoke and toxicity testing procedures under the condition of high temperature and smoke density detection materials smoke toxicity.The average optical density ratio requirement of flue gas(Dm)≦200;The smoke toxicity concentration was less than the limit value in table 2. According to the 2010FTP rules of Annex 1 second part 5--Material testing for pocedures for combusion,See Table 3 for specific requirements. Storage:The material must be stored in damp-proof packing and keep dry,the packing meet the need of military standard. Characteristic Lable the message in the corner of every panel as follow: 1、Material standard number,type,specification. 2、Lot No.and date of producted. 3、Lot. 4、Logo of company. 5、Order No.(out packing only) 6、Quantity of load(out packing only) 7、Production address.
