Background

  • Wool – Naturally flame retardant and used to meet stricter OEM FST requirements.

  • Used extensively outside USA

  • Conventional Nylon – Brominated Flame retardants – meets FAA standards.

  • Used extensively in USA

  • Summary:

  • Wool – Good FST Performance – Poor Operational Performance.

  • Meets OEM FST requirements

  • Nylon – Excellent Operational Performance – High smoke and toxic gases.

  • Up to 5x ware improvement

  • AkroBak Nylon – The best features of wool and Nylon
