Low Outgassing Silicones for Space Applications

From seals to thermal management, silicones are vital to spacecraft, but even small amounts of outgassed material cause serious issues. Space grade silicones therefore are critical for spacecraft reliability and performance, with low outgassing silicones being specially formulated to minimize volatile content and meet NASA standards.

TECHSiL are an authorised distribution partner of Momentive Performance Materials, supplying high-performance RTV silicones for low outgassing applications.

Benefits of Low Outgassing RTV Silicones:

• Loss of <1% of mass in a vacuum
• UV & ozone resistance
• Room temperature cure
• Excellent thermal insulation
• Remain flexible in extremely low temperatures
• Meet or exceed ASTM E595 testing standards
• Available in various viscosities
• Typical temperature range of -115°C up to 260°C

Momentive and the Space Industry
