F04Thermal insulation

Limit unwanted radiative heat exchange.

Manufacturers & products

Buy a finished, fitted multilayer-insulation blanket from a fabricator or source its films, spacers and closure materials separately. A reflective sheet is one layer; blanket performance also depends on seams, compression, penetrations and installation.

These are sourcing candidates, not a confirmed Starlink supply chain.

What remains unverified

  • Public data rarely establish fitted-blanket effective emittance, price or delivery time.
  • No blanket pattern or confirmed manufacturer for the modeled satellite is known.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

  • Effective blanket emittance

    Compare assembled-blanket performance at defined hot/cold boundary temperatures, not film emittance alone.

  • Layer stack & spacer design

    Specify materials, layer count, spacing and compression at attachments.

  • Mass per area · g/m²

    Include spacers, outer fabric, edge closures and grounding tabs.

  • Temperature & environment

    Check film, coating and adhesive limits plus atomic-oxygen/UV exposure.

  • Outer-surface optical properties

    Compare absorptance/emittance and their end-of-life degradation.

  • Grounding & charge control

    Define conductive paths, coating continuity and bonding points.

  • Venting & seams

    Review evacuation paths, edge leakage and penetrations around hardware.

  • Mechanical fit & installation

    Request blanket patterns, attachment features and access for integration.

  • Cleanliness & material traceability

    Ask for outgassing evidence, handling controls and material certificates.

Selection & integration notes
  • The catalog separates finished blankets from upstream films, tapes and spacer materials.
  • A layer's measured emittance cannot be used as the complete blanket's effective emittance.
  • For a particular spacecraft, blankets are usually patterned around actual interfaces and keep-outs.
