Bismaleimide resins are known for their high-strength and high-temperature performance. Their performance lies between lower temperature resistant epoxy systems and very high temperature-resistant polyimides. They are widely used as matrix resins for high-performance (fiber-reinforced) composites in electronic and aerospace industries.
They also find applications as high performance adhesives. Very often these reactive polymers require high curing temperatures of more than 150°C and long curing times.
Main applications: Paint and Coating Manufacturing, Plastics Material and Resin Manufacturing, Rubber Product Manufacturing
