Cosmic Shielding

Plasteel® is empowering the next generation of compute in space by protecting COTS GPUs, sensors, and AI payloads for reliable operation in the harshest radiation conditions.

PROVEN ACROSS THE HARSHEST RADIATION ENVIRONMENTS

Plasteel® is a proprietary, ultra lightweight, hydrogen-rich nanocomposite developed primarily to protect sensitive electronics from operational effects and the cumulative long-term damage and harmful effects caused by protons, neutrons, electrons, and heavy ions.

It has been optimized for shielding against radiation from both primary and secondary components of Trapped Particles, Solar Energetic Particles, and Galactic Cosmic Rays.

5x FEWER ERRORS, SAME THICKNESS

Plasteel fits seamlessly into existing architectures/designs/systems, providing dramatic error reductions at the same form factor.

Tested with LTC6240 and LT1499 Reference Opamps

8x longer to failure

Plasteel® is engineered to extend mission life in LEO, MEO, GEO, and beyond without redesigning your system architecture or sacrificing performance.

80%
fewer critical errors

Plasteel® is proven to reduce Single Event Effects across a wide range of spaceborne COTS systems.

Adaptable for Every Mission Profile

Plasteel® can be easily customized to fit any geometry or subsystem using 3D printing, injection molding, machining, and more. It significantly reduces mission costs and expands payload flexibility by requiring significantly less mass and volume than aluminum to meet mission TID and SEE requirements.
