Reinforced Graphite Gasket Sheets 1.0-3mm with Low Outgassing for Space Cryogenic Systems
Premium reinforced graphite gasket sheets specifically engineered for space exploration and cryogenic research systems. Available in 1.0 to 3mm thickness variants, these low-outgassing gaskets meet stringent requirements for ultra-low temperature environments where gas emission control is critical.
Dual-layer pure flexible graphite sheets sandwich a 0.2-0.25mm perforated metal insert for structural reinforcement. Metal core options include carbon steel (tinplate) or alloys like SS201, 304, 316. Available in carbon purity grades of 95%, 97%, 98%, or 99% to match specific outgassing requirements.
Integrated structure eliminates delamination risks while maintaining high yield strength. Ideal for cryostat flange seals and vacuum manifold applications. Low-outgassing properties maintain ultra-high vacuum conditions in space-rated equipment.
Engineered to withstand extreme temperature fluctuations from -196°C (liquid nitrogen) to cryogenic helium systems. Maintains dimensional stability in cyclic thermal conditions for superconducting magnet installations and space telescope cryocooler interfaces.
Oil-resistant composition ensures reliable performance with cryogenic fluids. Chemically inert to prevent compatibility issues with liquid oxygen, hydrogen, and other cryogenic media.
Available from 1.0-6.0mm, with specialized 3+2 composite designs (Paper-Metal-Paper-Metal-Paper cross-section) for thicker requirements. Multi-ply bonding technology ensures structural integrity in heavy-duty applications.
