THERMAL TAPE C
This new thermal tape is providing impressive thermal and electrical insulation for battery systems
ontaining thermal energy is a growing issue within the automotive industry, especially in the realm
of electric vehicles (EVs) and battery technology. Making safe and usable batteries is contingent on the manufacturer’s ability to contain thermal energy and prevent overheating. Thermal protection systems (TPS)
provider Blueshift has thrown its hat into the mix of solutions, having unveiled its new AeroZero lightweight thermal protection tape. These tapes are designed to slow temperature increases in battery systems. Surrounding components are
safeguarded using the tape, therefore mitigating the risk of damage and thermal runaway, creating a safer end product. AeroZero tapes are designed to
slow temperature increases in battery systems. Application is ideal in battery boxes, busbars, and other sensitive components within battery systems. It is suitable for use where exposure to high and fluctuating temperatures can impact safety and structural integrity. Both thermal and electrical
insulation can be achieved by using AeroZero tape as it offers robust protection during cyclical heating events which occur during operation and charging. Tim Burbey, president of Blueshift, underscores the company’s expertise in mission-critical industries like space and commercial aerospace, which reinforces the tape’s reliability. Burbey says: “We’re applying our
insights to offer AeroZero tapes to engineers and OEMs developing systems where thermal protection is paramount. This solution is especially valuable for designs with space limitations, cyclical temperatures, or those needing an easy-to-apply thermal barrier.” The tape has stood the test of
space, having proven itself in both spacecraft and aircraft applications. AreoZero was designed with engineers

www.engineerlive.com The AeroZero tape portfolio consists of a range of thermal and low dielectric products
in mind, making it easy for them to use. Product designers, manufacturers, and research and development teams can also take advantage of its applications. Teams focused on finding solutions in aerospace and defence can leverage the tape’s lightweight properties, as these industries prioritise weight reduction, safety, and ease of application. Burbey adds: “With virtually limitless
design possibilities, AeroZero tapes help enhance product safety and protect brand reputation. Our tapes support safe and reliable thermal protection for components that require precise, high-performance materials.” Extreme temperatures of 2,400°C
can be withstood for one to two minutes, providing high-temperature durability in a lightweight and slim profile. The tape is available in three

adhesive types; low outgassing, medical grade, and high temperature. The tape can have graphite,
polyimide, VDA polyimide, or metals added as an additional functional layer. The tape itself is composed of 85% air and has a polymer aerogel structure – this allows the tape to be thin but porous. Blueshift refers to its technology as ‘structured air’ due to its nanosized pores and good mechanical strength. Rolls can be customised to customer
needs, with all roles beginning with at least one 165-micron 6.5mil layer, and standard roles featuring a 25.4-micron 1mil pressure-sensitive adhesive. Blueshift claims one layer of their tape offers the same resistance as 20 layers of standard polyamide tape, along with seven times less thermal and electrical conductivity.
