  • Fiber mat is flame resistant
  • Base mat has high temperature stability (up to 1200°C)
  • Compressible material can fit into specific gap/pressure for assembly and operation
  • Compressibility allows for flexibility as battery cells expand and shrink during cell cycling
  • Thin, non-classified fiber mat material
  • Good electrical resistance
  • Good dielectric performance
  • Thermal conductivity of < 0.045 W/m·K at 25 °C (mat only)

3M™ Thermal Runaway Barrier 600/700 Series is a compressible, flame resistant, thermal insulation mat material that can be applied between cells to help reduce thermal transport in high temperatures. The base mat has high temperature stability (up to 1200°C) that allows material to maintain structural integrity and retain barrier performance. The mat features non-classified fibers, has good electrical resistance, and is designed to help slow down heat transfer from one cell to the next. In fully encapsulated form, the material provides good resistance to abrasion and particle shedding and can be customized to include single, or dual-sided, PSA layers for assembly.
