Hexcel® HexFlow® RTM250ST Mono-component Epoxy System
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Description: HexFlow® RTM250ST is the new generation mono-component aerospace resin system specially developed for Liquid Composite Molding applications, particularly RTM processes. HexFlow® RTM250ST is ideal for engines applications, such as fan blades, containment cases and OGVs due to its high toughness, long term thermal stability & exceptional Tg of 170°C. HexFlow® RTM250ST can be used in combination with a wide range of HexForce®, 2,5D & 3D fabrics. If needed, binders and veils are also available and fully compatible with HexFlow® RTM250ST. They provide easy preforming properties, reinforcement dimensional stability and toughening properties. Advantages Low moisture absorption: < 1,5% High toughness & high rate impact resistance Glass transition temperatures: dry1: Tg>170°C; wet2: Tg>150°C Tg long-term thermal stability Information provided by Hexcel Corporation.
