Solvay CYCOM® 5250-4 RTM BMI Resin, Unreinforced
Categories:	Polymer; Thermoset; Bismaleimide (BMI)
Material Notes:	CYCOM® 5250-4 RTM is a true one-part homogeneous BMI resin developed specifically for the resin transfer molding (RTM) process. It reaches very low viscosity during transfer and maintains a low viscosity for several hours, thus providing the maximum capability to fabricate complex parts. Laminates fabricated from CYCOM 5250-4 RTM are capable of service temperatures up to 400°F (204°C), but its toughness and processability make it an ideal material for 180°F (82°C) temperature applications where epoxies are commonly used. CYCOM 5250-4 RTM offers the highest open hole compression (OHC) value of any organic matrix resin while providing the highest level of toughness available in an RTM capable matrix resin. Features & Benefits: Excellent toughness Maximum continuous service temperature up to 400°F (204°C) Superior hot/wet properties at 160 to 375°F (71 to190°C) Low viscosity during processing Low-tack, solid at room temperature provides ease of handling Low thermal conductivity Versatile cure, can be cured at 400°F (204°C) for 2 hours Out-time greater than 60 days at room temperature True one-part formulation Fully compatible CYCOM 5240-4 RTM low resin content prepregs and CYCOM 782 RTM bindercoated fabrics are available for preform manufacture Applications: Wing stabilizer spars Fuselage skins and stiffeners Low operating temperature, critical load-bearing components Engine components Information provided by Cytec, subsequently acquired by Solvay.
