Flame Retardant Polycarbonate Sheet
B1 rated, ignition point 580 °C, self-extinguishing, no toxic smoke — for rail, public interiors and guarding.
Polycarbonate is inherently difficult to burn. Our standard sheet reaches a B1 rating, ignites only at 580 °C, self-extinguishes when the flame is removed, and does not release toxic gas or contribute to flame spread.
For applications where B1 is not enough, we supply V0-rated sheet compounded from V0 resin — not surface-treated. Surface treatments pass the initial test and fail after cleaning; compounded flame retardancy goes through the thickness and does not wash off.

Minimum order and lead time
This grade ships from 100 m² or 1 tonne — a trial pallet, not a full container. Standard sizes and stock colours run in 7–10 days; non-standard thickness or width in 12–18 days; add 3–7 days for CNC cut-to-size work. Quoted in USD on FOB, CIF or DDP terms.

Questions buyers ask
Is the flame retardancy a coating?
No. It is compounded into the resin so it runs through the full thickness of the sheet. Coated flame-retardant sheet loses its rating once the surface is abraded or cleaned repeatedly — which is exactly what happens in service.
Can you supply test certification?
Yes. Tell us which standard your project is assessed against — EN, ASTM, UL or a national equivalent — and we will confirm what documentation we can provide before you order.
Does flame-retardant sheet look different?
Clear FR grades carry a very slight tint compared with standard clear polycarbonate. In opal, grey and coloured grades there is no visible difference.
