Key highlights

In space-based applications, SQUID3's AgFEP tape is suitable for use as a single-layer Flexible Optical Solar Reflector (FOSR). It is ideal for LEO missions with operating temperatures ranging from -150°C to 125°C.

Applications

Spacecraft Thermal Control
Second Surface Mirrors
Quantum Computing
Cryogenic Flexible Cables

Key features

Optical Performance

Solar Absorptance: <14%
Infrared Emittance: 75-85% (depending on film thickness)

Customization

Film thickness is available in 5 or 10 mil. Maximum film width is 48 inches.

Flight heritage

Flight-proven materials

Manufacturing

Magnetron sputtering is one of the most widely used techniques for producing thin-film coatings. In this process, a dense plasma confined within a magnetic field generates a stable flux of sputtered silver atoms that deposit onto the Teflon FEP substrate. The resulting thin silver layer condenses uniformly on the Teflon, providing a reliable, high-reflectance Silver Teflon FEP tape.

Testing & qualification

This product meets NASA requirements for low thermal vacuum outgassing (ASTM E-595) where TML <1.0% and CVCM <0.1%.
