Battery Electric Vehicles

As a Tier 1 automotive industry supplier with nearly 25 years of aerogel manufacturing expertise, we know how to engineer thermal propagation solutions for your entire vehicle portfolio.

Our flexible PyroThin® technology platform makes aerogel accessible for every OEM

  • Entry-level EVs

    Meet industry thermal runaway standards such as China’s GB38031 and the United Nations’ ECE/TRANS/180/Add.20.

  • Mass-market Vehicles

    From LFP to high-nickel NMC solutions, our PyroThin portfolio spans a wide range of thickness and stiffness profiles that can be further optimized and quickly go into volume production.

  • Luxury & Performance

    Ultra-fast charging (800V+) and energy-dense packs generate extreme thermal and mechanical stress. PyroThin cell pads deliver performance in an ultrathin, featherlight format.

  • Plug-in Hybrid (PHEVs)

    PyroThin thermal barriers’ resilient mechanical performance is tuned from the aerogel itself, which can support cell health throughout the battery pack’s lifecycle.

Engineered for the toughest challenges, optimized for every EV

Stop thermal runaway propagation

PyroThin cell barriers can stop thermal propagation at a cell-to-cell level, enabling your team to focus on gas management, which is key in a non-propagating design.

Simplify your thermal runaway strategy

We take a system-level approach to design, delivering the thermal performance you need at EOL and ensuring proper support to maintain cell health throughout a pack’s lifecycle.
