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. Compimide Bismaleimide Monomers as the main ingredients for various bismaleimide resins:

Compimide® Toughening Modifiers have been designed for use with Compimide® Bismaleimide Monomers especially to enhance the processing as well as toughness of cured Composites:

Compimide® Formulated Bismaleimides Resins: The proprietary Compimide® Formulated Bismaleimide systems have been tailored for use in several different processing techniques. The incorporation of monomers, toughening modifiers as well as preparation know-how ensures the unique performance of the final composite. Compimide® Formulated Bismaleimide systems are available as a resolidified melt, as a powder, or as a solution.
