Bismaleimide monomers are difunctional compounds containing two maleimide rings (C=CC(O)-NH-). They are known for their high thermal stability and excellent mechanical properties. The main use of bismaleimide monomers is in the production of high-performance thermosetting resins for aerospace and automotive applications. Their ability to form crosslinked networks makes them ideal for composites that require high heat resistance and strength. Applications also include adhesives, coatings, and electronics, where thermal stability is critical.
