Beta cloth, also called beta fabric, is a white, PTFE-impregnated glass cloth commonly employed as an outer MLIB (Multi Later Insulation Blanket) layer due to its AO (atomic oxygen) resistance in LEO (Low Earth orbit). It was heavily used on the Space Shuttle and continues to protect the interior and exterior of the International Space Station (ISS).
This historic material is manufactured by Saint-Gobain Coated Fabrics in Manchester, NH USA and is supplied to the aerospace market exclusively by Bron Aerotech, Inc in Denver, CO. Bron Aerotech facilitated the successful re-qualification of beta cloth at aerospace OEMs when DuPont changed the Teflon formulation to reduce and then eliminate PFOA.
We supplied NASA (JPL) with beta cloth that is still protecting the nuclear power plant of Curiosity on planet Mars, 32 million miles from Earth.
The most common end products associated with beta cloth (non-silicone) are:
BA 500BC / CF500 raw beta cloth
Etched beta cloth for bonding and laminating
Beta cloth tape for cable/wire wrap
BA 500BC-966 beta cloth with low outgassing adhesive
BA 500BCGW beta cloth with graphite wire/weave for conductivity/anti-static
BA 125BCL light weight beta cloth (also available with graphite weave)
Metalized (VDA) beta cloth
Beta Cloth on Space Station during EVA (Space Walk).
Beta cloth, aka beta fabric, was designed and manufactured to withstand the harsh environment of space in order to protect sensitive and expensive equipment. It was at one time used in space suit manufacturing.
April 25, 1990, photograph taken by the crew of the STS-31 space shuttle mission, the Hubble Space Telescope is suspended above shuttle Discovery’s cargo bay some 332 nautical miles above Earth. The Canadian-built Remote Manipulator System (RMS) arm, controlled from in-cabin by the astronaut crew members, held the huge telescope in this position during pre-deployment procedures, which included extension of solar array panels and antennae.
