Hexcel® HexPly® F655 Bismaleimide Resin
Categories: Polymer; Thermoset; Bismaleimide (BMI)
Material Notes: HexPly® F655 is a bismaleimide resin that cures via an addition reaction in a toughened two-phase thermoset matrix with no condensation by-products. HexPly® F655 is a controlled flow polyimide resin system designed for alternative processing capabilities such as co-curing over honeycomb core, compression molding, as well as standard autoclave processing.
