Compimide® Bismaleimides


High-performance materials helping you to meet your future requirements for advanced composites today.


Evonik offers more than 30 years of experience in the field of bismaleimide resins. Our products are certified and referenced throughout the industry.

The Compimide® Bismaleimide resin family represents a full range of proprietary thermosetting resins and specialities developed for the production of high-performance composites, adhesives and moldings. Compimide® Bismaleimide matrix resins can be characterized by their high glass transition temperature (Tg). They offer improved high temperature performance over epoxies and cyanate esters. Other outstanding features are:
  • Easy processing by autoclave, platen press, and compression molding techniques
  • Retention of excellent mechanical properties up to 250 °C
  • Good solvent resistance
  • Excellent performance in hot / wet conditions
  • Superior flame and radiation resistance, low smoke and toxicant emissions
 
Typical processing techniques include prepregging (from the melt, solution, or suspension), resin transfer molding (RTM), filament winding, compression molding, powder coating, and pultrusion.
The Compimide® Bismaleimide product group comprises Compimide® Bismaleimide monomers, toughening modifiers and formulated bismaleimide resins.
