I.S.T. Unveils White TORMED for Smarter Spacecraft Thermal Control

I.S.T. Corporation has introduced White TORMED®, a new white polyimide film platform designed for spacecraft thermal-control applications. The company presented the technology at the 40th Annual Small Satellite Conference (SmallSat 2026), highlighting its potential to combine thermal-control performance with simplified spacecraft manufacturing.

The development of White TORMED® stems from I.S.T. Corporation’s 45 years of expertise in polyimide materials and the continued advancement of its TORMED® platform for space applications. The company explored whether thermal-control functionality could be incorporated directly into a lightweight, flexible polyimide film rather than relying on conventional surface coatings. This approach resulted in White TORMED®.

The new material is supplied as a finished film with controlled thickness, low weight, and repeatable thermal characteristics. Its film-based format could reduce manufacturing complexity by replacing multiple coating, curing, and drying stages with direct film application. At a thickness of just 25 microns, the technology is designed to provide consistent coverage across spacecraft surfaces, including edges and corners, while adding minimal mass.

White TORMED® is also a non-fluoropolymer film designed for integration with composite structures and functional layers, including metals. I.S.T. is developing a patent-pending technology that enables the film to be co-cured with prepreg without adhesives, potentially eliminating additional bonding processes and simplifying assembly.

The platform builds on I.S.T. Corporation’s transparent TORMED® polyimide film, which offers optical transparency, flexibility, electrical insulation, low outgassing, and compatibility with deposited metals and other functional layers. Transparent TORMED® has undergone independent space evaluations and has been exposed to orbital conditions.

Samples participated in the Euro Material Ageing (EMA) experiment, conducted on the International Space Station’s Bartolomeo external platform through collaboration involving CNES, CNRS, and ESA. The samples spent about one year in orbit before returning to Earth, with post-flight evaluation continuing.

Transparent TORMED® has also been selected as a protective cover film for silicon solar modules used in commercial satellites, supporting the transition from technical validation toward commercial applications.

I.S.T. Corporation is now pursuing a phased commercialization strategy for White TORMED®. A4 sheets are currently available for evaluation, while pilot production of 300-mm-wide rolls is targeted for November 2026. The company plans a market review and investment decision in September 2027, followed by a conditional target for mass production of rolls wider than 1,000 mm in fall 2028.

These milestones remain dependent on evaluation results, market demand, technical readiness, and investment approval. The company is inviting spacecraft manufacturers, subsystem suppliers, and integrators to assess White TORMED® for potential thermal-control and functional-film applications.

Product Impact and Chemical Commodity Price Impact

White TORMED® could strengthen I.S.T. Corporation’s position in advanced aerospace materials by offering spacecraft manufacturers a lightweight, flexible, and potentially faster-to-install thermal-control solution. If adoption expands, demand for high-performance polyimide films, specialty polymers, engineering plastics, and functional coating materials could increase, particularly in aerospace applications. However, near-term effects on commodity prices tracked by ChemAnalyst are likely to remain limited because the product is still moving through evaluation and pilot-scale development. Successful commercialization could gradually support firmer prices for specialty polyimide resins and films, while broader commodity polymers would likely see minimal direct impact due to the relatively small aerospace demand base.
