Product Description

Reinforced Graphite Gasket Sheets with Low Outgassing for Space & Research Cryogenic Systems

Seeking premium reinforced graphite gasket sheets tailored for space exploration and cryogenic research systems? Your search ends here. Our low-outgassing gasket solutions, available in 1.0 to 3mm thickness variants, are meticulously engineered to meet the stringent demands of ultra-low temperature environments where gas emission control is critical.

Key Product Attributes

Enhanced Longevity Construction

Crafted with dual-layer pure flexible graphite sheets sandwiching a 0.2 - 0.25mm perforated metal insert, these gaskets deliver unmatched durability. The metal core—typically 0.2 - 0.25mm carbon steel (tinplate) or optional alloys like SS201, 304, 316—provides structural reinforcement. Choose from carbon purity grades of 95%, 97%, 98%, or 99% to align with your system’s specific outgassing requirements.

Optimal Sealing Efficiency

Designed for superior adaptability, these gaskets ensure hermetic seals in cryogenic setups. The integrated structure eliminates delamination risks while maintaining high yield strength, making them both a technical and cost-effective choice for cryostat flange seals and vacuum manifold applications. Their low-outgassing property is particularly vital for maintaining ultra-high vacuum conditions in space-rated equipment.

Extreme Environment Resistance

Engineered to withstand extreme temperature and pressure fluctuations, these gaskets excel in liquid nitrogen (-196°C) and cryogenic helium systems. They remain dimensionally stable in cyclic thermal conditions, making them ideal for superconducting magnet installations and space telescope cryocooler interfaces.

Chemical Inertness & Fluid Resistance

The oil-resistant composition ensures reliable performance in cryogenic fluid sealing tasks, such as cryogenic pump housings and rocket engine fuel line connections. Their chemical inertness prevents compatibility issues with liquid oxygen, hydrogen, and other cryogenic media.

Product Dimensions & Customization

Thickness Options

Ranging 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.

Standard & Custom Sizes

Stock sizes include 500×500mm, 500×1000mm, 500×1500mm, 1000×1000mm, and 1000×1500mm. We also offer precision-cut custom dimensions to match unique cryogenic vessel configurations or space hardware interfaces.

Material Selection Guide

For optimal performance in cryogenic systems, select the thinnest viable thickness to minimize thermal conductivity and outgassing volume. Unsure about material grade or thickness? Consult our cryogenic gasket selection tool or thermal management guide for data-driven recommendations.
