Flame Retardant Polycarbonate Sheet

B1 rated, ignition point 580 °C, self-extinguishing, no toxic smoke — for rail, public interiors and guarding.

Industry Applications

Used for EV charging stations, equipment guards, bus shelters, curtain walls, outdoor signs, daylight roofs, skylights and stadium barriers.

Bus Shelters

New Energy Vehicle Charging Stations

Equipment Protective Covers

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.

Product Features of Flame Retardant Polycarbonate Sheet

High Impact Resistance

High strength and impact resistance make the sheet tough, safe and difficult to break. The source product page positions it for protective and security glazing.

Good Weather Resistance

The source page states that the sheet does not become brittle at -30°C or soften at 120°C, with mechanical performance remaining stable in harsh conditions.

Flame-Retardant Performance

The source page describes B1 flame-retardant performance, self-extinguishing behaviour after removal from flame and no promotion of flame spread.

High Light Transmission

Light transmission can reach up to 90%, providing glass-like transparency where a clear grade is specified.

UV Protection

A UV-protective surface layer helps reduce yellowing during long-term sunlight exposure.

Sound Insulation

The source page states 5-9 dB more sound insulation than glass at the same thickness and references noise-barrier use.

Minimum order and lead time

Plastura supplies flame retardant polycarbonate sheet from its Jiangsu plant. For an accurate quote, state thickness, finished size, colour or surface requirement, quantity, and any cutting or forming. Standard stock sizes and colours normally run in 7–10 days; non-standard extrusion in 12–18 days; allow another 3–7 days for CNC work. The published starting point is 100 m² or 1 tonne, quoted in USD on FOB, CIF or DDP terms. See MOQ, lead time and shipping for planning details.

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.
