Low Smoke Fire Resistant Floor Coverings:Low Smoke Fire Resistant Floor Coverings:

  •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
