Heat Shield HS900 Series

High Performance Heat Shield with Superior Thermal Insulation

With minimum installation space, our product enables the fulfillment of legal safety demands, e.g. GB 38031-2020. We offer fully engineered, standard or tailormade solutions to meet customer requirements, which are validated in our state-of-the-art laboratory.
Our HS900 series is the leading heat shield technology for lithium-ion battery systems. It is a heat shield made out of ultra-thin and lightweight material, which provides continuous high-temperature resistance of up to 1400°C even with a hot gas particle impact.

Additionally, the excellent thermal and electrical insulation permits the use of a lightweight cover with low-temperature limits, for example, SMC or aluminum. HS900 has also 3D-formability, which enables a customized and compatible integration into the battery system environment.

  • Protecting passengers from fire, heat and gases
  • Enabling occupants more time to exit
  • Light-weight solutions compared to alternative products
  • 3D-Formable and machinable to suit individual packaging requirements
  • Suitable as well for drop in upgrades due to 0.8. to 2.5 mm thickness

Protects Occupants in Case of Thermal Runaway Events from Lithium-Ion Batteries

Oerlikon Friction System's advanced Research and Development center has developed a thermal performance test, simulating a thermal runaway event quickly and efficiently without having to use a complete battery system. With such a test, we are able to provide proven unique solutions to our customers as well as allowing pre-validation of the heat shields performance, therefore minimizing the requirement for full battery tests. By doing this, Oerlikon Friction Systems is pioneering the industry test standards for:

  • Temperature resistance
  • Thermal insulation performance
  • Resistance to hot gas particle impact

In this video you will see that a heat shield with the HS900 series materials can withstand a flame with thousands of Celsius degrees for as long as 10 minutes without having an impact on the heat shield.
