Underwriters Laboratory (UL) details…
Standard Xantar grades have ratings of V2 in all colours at minimum
thicknesses of 0.75mm. For high flow grades the minimum thickness for V2 is
1.5mm. Xantar FR grades all have V0 ratings at a thickness of typically 1.5mm.
• Special grades meet the stringent 5VA and 5VB criteria at thickness from 2
- 3mm (depending on type)
GWI (Glow Wire Ingnition) to meet e.g.
IEC 60335-1
Most Xantar FR grades have a rating of 960C at 1.5mm.
Xantar C
FR grades similarly have 960C ratings at 1.5mm
Standard Xantar® C non
FR grades are typically rated at 750C
Limiting Oxygen Index (LOI)
This is an indication of self
extinguishing behaviour. Grades whose LOI values are above about 20% (typical
level of oxygen in the atmosphere) will self-extinguish as the oxygen
concentration in the air is insufficient to sustain the flame. The higher the
value the better the self extinguishing behaviour. Typical Xantar levels are
- FR Xantar and Xantar C >30
- unfilled standard
Xantar 28
- standard Xantar C
23
