SSLC has developed an innovative, award-winning line of all-composite cryogenic tanks called Pressurmaxx, which is characterized by carbon fiber material and SSLC’s proprietary cryogenic resin formulation, termed Sapphire77. Tanks can be built in a wide range of sizes and aspect ratios for different applications. The tanks have been successfully tested at cryogenic temperatures down to –321 deg F, and at pressures up to 8,000 psi. This high performance is available at lower cost and shorter lead time than traditional composite-overwrapped pressure vessels (COPV) or metallic tanks. The SSLC composite tanks are characterized by patented technologies like all-composite polar bosses (including the boss threading), incorporation of external structural stringers and internal slosh baffles, and special tooling production. The tanks are unibody structures and can become the primary structure of a launch vehicle or a spacecraft. Additionally, SSLC also commercially sells tanks incorporating a positive expulsion device (bladder), which is used for spacecraft in-space propulsion. The applications of the Pressurmaxx tanks are not limited to space, but span the Aeronautics, Unmanned Aerial systems (UAS), Unmanned Underwater Vehicles (UUV), automotive, Energy, industrial, medical, military, and special ops fields, and possibly more.
