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
