6FDA is the most preferred synthesis of fluorinated polyimide two anhydrodemonomer.The hygroscrocopicity and dielectric constant of fluorinated polyimidewith 6FDA are less than others.Meanwhile,being dissoluble,6FDA is necessary forproducing colorless and transparent polyimide two anhydride monomer.
Packing:Bag,Drum,Carton
Storage: In the packaging integrity conditions,it can be placed in adry,ventiliated environment in three years.
