F650

A Bismaleimide Resin for Advanced Composites

BMI F650 - 37685 Product Data

Description

HexPly
® F650 is a bismaleimide resin that cures via an additional/free radical mechanism resulting in a cross-linked thermoset system with no condensation by-products. HexPly
® F650 was developed by Hexcel to overcome existinglimitations for use on complex structures and ducting in advanced military aircraft, helicopters, and many other high temperature applications. HexPly
® F650 simplifies fabrications and delivers a more cost-effective end product. A New Level of Workability Designers can now specify BMI in structures with extreme curvature without performance worries because HexPly
® F650 offers excellent tack, handling characteristics, and straightforward layup and processing. In addition,there is no unpleasant odor and no need for cumbersome layup aids. Longer Out Time You have more time to work with HexPly
® F650. The out time for successful structure layup is measured in weeksrather than days. And that’s time that allows for more complex applications. Straight-Up Curing You won’t have to babysit HexPly
® F650. Employ simple, straight-up cure cycle followed by conventional postcureand that’s it. HexPly
® F650’s unique resin chemistry also eliminates micro-cracking. HexPly
® F650 delivers consistentvoid-free laminates time after time. Superior Burn Characteristic HexPly
® F650 takes the heat, remaining structurally stable up to 600°F (316°C) dry, and 450°F (232°C) wet. It emitsminimal visual smoke and possesses excellent fire barrier properties. HexPly
® F650 is currently being evaluated for avariety of fire containment structures. Desirable Electrical Performance HexPly
® F650 possesses excellent electrical properties, characteristic to polyimide resin systems, and is the ideal candidate for radome and other electronic applications.
