Raptor Resins’ advanced bismaleimide (BMI) resins deliver exceptional thermal stability, mechanical strength, low dielectric properties, and flame retardancy. These characteristics hold strong even under continuous use at temperatures up to 260°C (500°F), and for short excursions as high as 400°C (752°F). While BMI resins are priced higher than alternatives like epoxy or phenolic, they outperform in demanding environments, offering superior value over thermoplastics and cyanate esters.

Demand for BMI resins is surging in high-stakes applications where reliability is non-negotiable:

• Aerospace: Ideal for components like brakes, engine bypass ducts, nozzle flaps, bushings, bearings, engine cooling tubes, and radomes.
• Defense & Weapon Systems: Used in missile structures, dorsal fins, and other heat-exposed parts.
• Space Vehicles: Withstands extreme temperatures in jet engines and re-entry conditions.

Carbon fiber composites infused with BMI resins surpass metals in strength-to-weight ratios, excelling in aircraft engine nozzles, nacelles, helicopter gear cases, and missile fins—especially at operating ranges of 232°C to 342°C (450°F to 650°F). Processed at lower temperatures and pressures than traditional high-temp materials, our BMI resins can slash manufacturing costs without compromising performance.
