polyimide chopped fiber

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,
