Polyimide Monomers

 Polyimide (PI) is at the tip pyramid of the engineering plastics pyramid and is known as "plastic gold". Fluorinated polyimide (CPI), also known as transparent polyimide, overcomes the shortcomings of PI material's light yellow or dark yellow color. It is the leader of PI materials. It has the characteristics of large deformation, best performance, and high optical transparency.

 

Being benefit of the convenience of the material of Hexafluoroacetone, We have developed a series of fluorinated polyimide monomers and other hexafluoroacetone derivatives. Among them, bisphenol AF has been industrialized in the factory, and 6FDA and bisphenol AF downstream polyimide monomers have completed kilogram samples.

• Bisphenol AF CAS No. 1478-61-1

• 2,2-Bis(4-aminophenyl)hexafluoropropane CAS No.: 1095-78-9

• 2,2-Bis(3-amino-4-hydroxyphenyl)hexafluoropropane CAS No.: 83558-87-6

• 2,2-Bis[4-(4-aminophenoxy)phenyl]-hexafluoropropanane CAS No.: 69563-88-8

•  2,2'-Bis[4-(4-amino-2-trifluoromethylphenoxy)phenyl]hexafluoropropane CAS No.: 94525-07-2

• Hydrogenated bisphenol AF CAS No.: 119170-78-4

• 4,4'-(Hexafluoroisopropylidene)diphthalic anhydride CAS No.: 1107-00-2

• alpha,alpha-Bis(trifluoromethyl)-4-vinylbenzyl alcohol CAS No.: 2386-82-5

• 2-vinylhexafluoroisopropanol CAS No.: 19701-19-0

Meanwhile, we had finished a series of Aliphatic dianhydride monomers:

• Cyclobutane-1,2,3,4-tetracarboxylic dianhydride CAS No.: 4415-87-6
