Blueshift launches AeroZero FTBs – ultra-light, high-performance flame & thermal barrier for next-gen electric and aerospace systems
Blueshift, a technology specialist in advanced thermal protection systems (TPS), has launched its AeroZero Flame & Thermal Barriers (FTBs), a portfolio of ultra-thin, lightweight and flexible flame and thermal material solutions that can withstand exposure up to 1200°C for 30 minutes.
With the continuing global adoption of electric vehicles (EVs) and aerospace electrification, Blueshift’s latest addition to its AeroZero family is suitable for a wide range of applications and industries that can experience extreme temperature fluctuations; from EVs and aerospace markets, to marine and rail.
For example, within the field of EVs, FTBs are primarily used as a safety barrier material aimed at preventing the transfer of extreme heat or fire that can result in mechanical damage of battery cells and exposure to high temperatures or discharge events. Blueshift’s AeroZero FTBs can withstand exposure up to 1200°C for 30 minutes whilst maintaining a cold-side temperature below 300°C. This means they can either be used as safety features in preventing uncontrolled fire, for example due to an aircraft engine fire, or protecting surfaces from direct exposure to flame such as during a rocket take-off or helping to mitigate the risk of a battery thermal runaway event.
Described as outperforming traditional mica, silica or polyurethane foams, AeroZero FTBs are said to be up to 80 per cent lighter, with a thickness range of 0.32 – 1.77mm – significantly thinner than conventional barriers (3-10mm), according to Blueshift. Alongside this, their ease-of-use and flexibility is a key factor influencing engineers’ decisions to integrate the new materials into their designs. With their ‘peel-and-stick’ pressure sensitive adhesives (PSA)-backing that simplifies installation on irregular surfaces, labour time and cost can be drastically lowered, the company added.
Tim Burbey, President at Blueshift, said that AeroZero FTBs aim to set a new benchmark within the industry: “Traditional thermal insulators have often been based on polymeric foams or ceramic blankets that can suffer from drawbacks due to their added weight, thickness, toxic off-gassing, lack of flexibility and processing issues. As EV adoption ramps us alongside aerospace electrification, our AeroZero FTBs will unlock new performance capabilities by enabling the next generation of aircraft and vehicles to be safer, lighter and more efficient.
“Available across multiple ranges, we look to incorporate as many vehicles and industries as possible, so everyone can overcome their unique thermal challenges that other FTBs in the market simply cannot.”
The AeroZero FTBs family includes, AZ-FTB 100 for up to 500°C applications, AZ-FTB 101 for up to 800°C and AZ-FTB 300 for maximum protection up to 1200°C. These advanced FTBs are suitable for protection in EV battery modules, and aerospace components that see indirect and direct exposure to flames.
