Classification4.1 The polyimide cellular insulations of the specificationare classified into Types I, II and III. Type I is polyimide foam

42、with a closed cell content of greater than 75 % and Type II isopen celled polyimide foam with a closed cell content of lessthan 30 %. Type III is polyimide foam with a closed cellcontent of between 20 and 75 %. The polyimide cellularinsulation is further classified into grades according to density.4
