Polyimide fiber with excellent properties of high temperature resistance, insulation, flame retardant, anti-radiation, anti- UV, anti-bacteria and solvent resistance can be widely used in the area of high temperature dusting(Non-woven felt, filter bag), special protection and composite material. The fiber is applied to a kind of inforcing material in the composite material to prolong the life time, Especially for the polyimide fiber paper.
The general index polyimide fiber is as follows,
Fineness 1.5~5 dtex,
Density 1.41 g/cm3 ;
Breaking strength >4.0 cN/dtex;
Elongation at break 10~30%;
Continuous use temperature 260ºC;
Decomposition temperature 560ºC;
Limiting oxygen index (LOI) 38%;
Acid resistance and UV radiation resistance.
