The fiber is with excellent properties of high temperature resistance, insulation, flame retardant, anti-radiation, anti- UV, anti-bacteria and solvent resistance. The fiber is used to be a kind of inforcing material in the composite material to prolong the life time, Especially for the polyimide fiber paper.
The general index of polyimide fiber is as follows,

Fineness   0.9~5 dtex,

Cut lengths:3mm, 6mm,12mm

Density     1.41 g/cm3 ;

Breaking strength ＞4.0 cN/dtex;

Elongation at break 10~30%;

Continuous use temperature 260℃;

Decomposition temperature 560℃;

Limiting oxygen index (LOI) 38%;

Acid resistance and UV radiation resistance.
