6FDA is the most preferred synthesis of fluorinated polyimide two anhydrode monomer.The

hygroscrocopicity and dielectric constant of fluorinated polyimide with 6FDA are less than others.Meanwhile,

being dissoluble,6FDA is necessary for producing colorless and transparent polyimide two anhydride

monomer.

Packing:Bag,Drum,Carton

Storage: In the packaging integrity conditions,it can be placed in a dry,ventiliated environment in three years.
