Heat protection, shielding, sealing: Our carbon and graphite solutions for critical missions

For demanding applications in aerospace, security, and defense

In demanding environments, from the edge of Earth’s atmosphere to mission-critical defense systems – materials matter. They must not only perform well, but also endure.

SGL Carbon offers a wide range of high-purity carbon and graphite materials designed for use in the most extreme conditions. No matter what sector the application belongs to - defense, security, aerospace, or space - our solutions deliver unmatched reliability and performance.

Our materials are enablers of innovation, safety, and resilience, not just components. They offer a unique combination of properties, making them indispensable across various industries:

Ablative behavior for thermal protection
High thermal conductivity for efficient heat dissipation
Radiation shielding to protect sensitive electronics and parts
Temperature and corrosion resistance for long-term durability under extreme conditions
High purity and quality for mission-critical reliability
Chemical inertness for stability in harsh environments
Lightweight for optimized structural performance

Rayon carbon fabric for thermal protection systems

Carbon rayon fabric characterized by its extreme temperature resistance and high-quality is used to produce carbon cloth polymer composites like phenolic resin-based materials. The composites are key for protecting structural components of rockets, space shuttles, and satellites from heat – functioning as ablative or sacrificial materials. They are critical to their safe operation.

High-strength SIGRAFLEX military grade graphite textile yarns for tight sealing

Materials used to manufacture products for military applications must have outstanding properties and meet the highest standards in terms of purity, chemical, oxidation, and temperature resistance. This ensures the final product is extremely safe, reliable, and long-lasting.

SGL Carbon’s expertise in the field of compression packing yarns has been gained over the last 50 years. We offer a broad SIGRAFLEX textile yarn portfolio with a variety of precursor materials, yarn plies, twists and coatings.

Depending on the specific application we offer both continuous filament graphite PAN and rayon yarns which are certifiable e.g. to the latest US Navy specification MIL-P-24583B.

Our materials are ready to meet your toughest challenges, whether you need to design next-generation propulsion systems, thermal shields, transport boxes, protective components, demanding protection or release layers, or efficient EMI shielding or high-performance heat management.
