SSP2575 is a 65-durometer silicone elastomer for low outgassing, low temperature applications in spacecraft. This product maintains its flexibility at temperatures as low as -116°C (-177°F) and passes ASTM E595 outgas testing with a Total Mass Loss (TML) of 0.17%.
The ASTM E595 Outgas test measured Total Mass Loss (TML), Collected Volatile Condensable Material (CVC) and Water Vapor Recovered (WVR). Historically, a TML of 1.00% and CVCM of 0.10% have been used as screening levels for rejection of spacecraft materials. SSP2575 was within these limits.
