SPACE / Structure & thermal / REVIEWED 2026-09-11
Reject waste heat to space.
Radiator sourcing includes custom panels, deployed assemblies and the optical films applied to their surfaces. Heat transport within the panel and radiation from its surface are separate performance questions.
These are sourcing candidates, not a confirmed Starlink supply chain.
Honeycomb panels incorporating constant-conductance heat pipes to spread equipment heat across the radiator surface. [1]
Use the manufacturer's linked product information to request a configuration-specific quotation and current availability.
Custom spacecraft radiator and thermostructural assemblies integrated with heat-transport hardware. [2]
Use the manufacturer's linked product information to request a configuration-specific quotation and current availability.
Deployable radiators incorporating macro loop heat pipes and mechanical assembly, integration and testing. [3][4]
Company location: Nivelles, Belgium
Use the manufacturer's linked product information to request a configuration-specific quotation and current availability.
Thermal panel capability with published DART radiator heritage from the former Boyd Thermal business. [5][6]
Use the manufacturer's linked product information to request a configuration-specific quotation and current availability.
Custom fixed or deployable radiator concepts integrating oscillating heat pipes into two- or three-dimensional panel constructions. [7]
Use the manufacturer's linked product information to request a configuration-specific quotation and current availability.
Development-stage radiator architecture combining a high-conductance hinge and an isothermal composite-skin panel. [8]
Company location: North Logan, Utah, USA
Contact TMT to establish current development status and whether a program-specific unit can be supplied.
Upstream metallized FEP surface materials for controlling solar absorption and infrared emission on radiator surfaces. [10]
Use the manufacturer's linked product information to request a configuration-specific quotation and current availability.
Metallized and coated spacecraft films and tapes that can be incorporated into thermal-control surface constructions. [9]
Use the manufacturer's linked product information to request a configuration-specific quotation and current availability.
A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.
Measure unobstructed area and the surfaces visible to it, including Earth and the Sun.
Compare rejection at the same panel temperature and orbital environment; watts alone are insufficient.
Ask for beginning- and end-of-life optical properties and the test method.
Check spreading performance between the heat input and the radiating surface.
Define embedded heat pipes, conductive joints, loops and any deployable hinge.
Compare the complete panel, coating, plumbing and deployment hardware.
Verify clearances, deployment reliability and launch packaging.
Assess atomic oxygen, radiation and coating degradation for the intended orbit.
Request thermal-vacuum correlation, leak testing where applicable, and structural qualification.
Specifications belong to the named product and configuration.
The sheet explicitly labels this technology under development and says the values are for reference, not design. Request a current qualified product definition.
A custom assembly example. Public page information does not provide a single model-specific wattage, mass or area; these belong in the supplier quotation and thermal model.
Manufacturer pages and technical documents support the linked claims. A review date is not a publication date or stock check.
