Product specifications

The ContraFlame® S2- Series combines a thin profile with superior fire and thermal runaway resistance properties. Even when tested with the most aggressive prismatic cells, it is proven solution. With a mica-free, low-density formulation, our ContraFlame® S2- Series is an advanced, lightweight thermal barrier material.

  • Tested up to 250 Ah, ContraFlame® S2- Series offers the highest level of protection even against the most aggressive battery cells
  • Protects against temperatures of over 1300 °C
  • Capable of being fitted to acute angles, our ContraFlame® S2- Series are ideal for complex geometric shapes
  • Lightweight - an important trait for increasing the range of a battery pack
  • Low smoke and toxicity during a fire
  • Its unique properties mean that, unlike intumescents, our ContraFlame® S2- Series stay the same thickness throughout a fire event.
