4,4'-(Hexafluoroisopropylidene)diphthalic anhydride

Abbreviated name: 6FDA Item No.: SolverPI-Monomer 6FDA CAS No.: 1107-00-2 MDL:MFCD00039143 Molecular Formula: C19H6F6O6 Formular Weight: 444.24 Physicochemical Property: White crystal or powder,can be dissolved in two dimethyl formamide,dimethylacetamide,N-methyl pyrrolidone,ethy acetatae,acetic anhydride,acetic acid,Slightly souble in ethanol,methanol,isopropanol and hot water(60-70℃)melting point244-247℃. 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.
