Key highlights

SQUID3 Space™ ITO Coated Silver AlphaFEP Tape is a conductive flexible film radiator technology capable of mitigating differential charging and electrostatic discharge (ESD). This product combines the proven thermo-optical performance of Ag/FEP with a transparent Indium Tin Oxide (ITO) conductive coating on the top surface. Also known as Silver Teflon® or Ag/FEP, SQUID3's Silver AlphaFEP is commonly implemented as a Flexible Optical Solar Reflector (FOSR). From LEO small satellites to mega constellations, Silver AlphaFEP is optimized for bonding on wide-profiled structural panels. On-orbit degradation is well-characterized by NASA, ESA, and JAXA in flight literature. Silver AlphaFEP incorporates FEP film exclusively extruded from Teflon® FEP 100 resin. Each lot ships with full material traceability and certificate of analysis.

Applications

Spacecraft Thermal Control

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 FEP, providing a reliable, high-reflectance silver coated 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%.
