Gasketing Foam Tape with Unique Sealing Properties

The Norseal® FS1000 Series from Saint-Gobain is a high-performance foam tape designed with a unique combination of properties that make it suitable for a variety of applications, including for the mitigation of thermal runaway in a battery module or between modules in a battery pack.


  • Expandable and fire-resistant: When heated to more than 200°C, FS1000 will expand and form a fire-resistant char, blocking fire, smoke and hot gases. The material does not contain any halogens and there are no concerns of toxic gas emissions when heated.

  • Airtight: Compressed by 30%, FS1000 is airtight up to a pressure of 1000 Pa, depending on the surface of the application.

  • Watertight: FS1000 is watertight when compressed by 30%.

  • Compressible and resilient: It can be easily compressed and comes back to its original thickness after compression. As a result of its resilience, FS1000 is able to damp vibrations and decouple two elements.

  • Conformable: Soft; will conform to uneven surfaces.

  • Insulation: Provides good thermal insulation.

Norseal FS1000 is available in different thicknesses and can be offered with adhesive on one side for easy installation. The material does not dust during installation, making it safe for workers and others nearby during the assembly process.
