NS-220 Ultra-Soft Silicone Foam

Liquid Silicone Foam

This ultra-soft silicone foam is a light, highly compressible foam that is perfect for applications including, sealing, vibration isolation, electronics and transportation. It is a direct comparable to Rogers Bisco® BF-2000 cellular material.

Most importantly, it offers UL 94 V-0 flame resistance and it’s low softness protects your seals while using less force. Your maintenance cost will be lower as gasket failures due to softening and compression set and  can be avoided

More Information

UL 94 V-0

  • UL 94 V-0 is a safety and flammability standard by Underwriters Laboratories.
  • This material is compliant with the UL 94 V-0 test standard for flammability.
  • The vertical burn test measures the self-extinguishing time of a vertically oriented polymer specimen. The test evaluates both the burning and afterglow times and dripping of the burning test specimen.
  • In order to be rated UL 94 V-0, the burning must stop within 10 seconds, no flame propagation or dripping.
