Core Positioning: With its outstanding comprehensive performance, PMI foam has become the core material for key structural components of launch vehicles, widely used in core parts such as rocket fairings, interstages, and instrument bays.

Lightweight Advantage: Density ranges from 0.03 to 0.12 g/cm³, which can reduce component weight by 30%-50% compared with traditional metal materials, effectively improving rocket propulsion efficiency and increasing payload capacity.

Strength and Stability: Tensile strength reaches 10-30 MPa, compressive strength is 8-25 MPa, with excellent deformation resistance, capable of withstanding severe vibration, impact load and aerodynamic pressure during rocket launch.

Temperature Resistance and Creep Resistance: Maintains stable performance in a wide temperature range of -50℃ to 120℃, with creep deformation less than 1% under long-term service, adapting to the extreme temperature cycle environment of rockets from low ground temperature to high-altitude high temperature.

Cost and Process: Compared with carbon fiber composite materials, raw material cost is reduced by 20%-40%, and it is easy to cut, form and bond, allowing customized processing according to the complex structure of components, shortening the production cycle and reducing manufacturing costs.

Environment Adaptability: Possesses good chemical corrosion resistance and radiation resistance, capable of resisting the erosion of rocket propellant residues, high-altitude ultraviolet rays and cosmic rays, ensuring the reliability and safety of components throughout their entire life cycle.

Application Verification: Has been successfully applied to key components of many domestic and foreign launch vehicles (such as the Long March series and Falcon series). Verified by actual launches, its performance fully meets the strict requirements of high reliability and high precision for rockets.
