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, 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.

CYCOM® 5270-1

CYCOM® 5270-1 is an advanced bismaleimide prepreg resin available with glass and carbon fabric, designed for high temperature use. CYCOM® 5270-1 has similar mechanical properties to CYCOM® 5250-4, has a damage tolerance equivalent to epoxy with low moisture absorption, does not produce any volatiles during the 375°F (190°C) cure and can be processed as RTM.

Liquid epoxy resin system. Available as a one-part system, with one working week out-life at room temperature so as to remove the requirement for customers to carry out resin mixing and its associated quality control processes. Its frozen storage shelf-life is 6 months at 0°F (-18°C). If extended ambient storage is required then the resin could be supplies as a two-part system. The viscosity is low enough at room temperature to allow injection without having to heat either the resin or the transfer pipework. When the resin is heated to the cure temperature its viscosity is further reduced, helping to ensure full wet-out of the reinforcing fibers. Fully cured after one hour at 255°F (125°C) giving a continuous dry service performance of 230°F (110°C) and a continuous hot/wet service performance of 195°F (90°C). 4-5 days outlife at 21°C (70°F) as a one-part. indefinite as a two-part system Product Form: epoxy | Out Time (days): 4-5 | Temp: 195 (90) | Cure Flex: 255 (125) | Process: vacuum | TG: 260 (125)
