## Developments in:

**Developments in:**
** ****	****	****- Low Smoke Fire Resistant Floor Coverings**
**	****	****- Low Smoke Fire Resistant Interior Repair Compounds**

**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***_*** ***
