Description

2,2-Bis[4-(4-Maleimidophenoxy)Phenyl]Hexafluoropropane (4Bapofp/Bmi) is a high-performance, fluorinated bismaleimide monomer. This compound is valued for its ability to impart exceptional thermal stability, low moisture absorption, and excellent dielectric properties to advanced polymer matrices. It is primarily sought by manufacturers in the aerospace, microelectronics, and high-temperature composite industries for creating next-generation polyimide resins, adhesives, and encapsulants. The material is light-sensitive and should be stored away from light.

Application

• As a key monomer for synthesizing high-temperature, fluorinated polyimide resins and films.
• In the formulation of advanced composite matrix resins for aerospace and military applications.
• As a crosslinking agent or curing agent in high-performance thermosetting polymers.
• For manufacturing electronic encapsulants and adhesives requiring low dielectric constant and high thermal stability.
• In the production of specialty coatings for extreme environments.
• As a precursor for modified polyimides used in flexible printed circuit boards (FPCBs) and microelectronics.
