Energy Storage Insulation Panels
Battery module barriers and electrical insulation — flame retardant, dimensionally stable, machined to drawing.
Battery energy storage puts three demands on a plastic part at once: it must insulate electrically, it must not propagate a fire, and it must hold its dimensions in a hot, vibrating enclosure. Polycarbonate does all three, which is why it appears throughout module construction.
For this work we supply flame-retardant grades compounded from V0 resin rather than surface-treated sheet, machined to drawing on our CNC centres.

Typical applications
- Battery module separators and end plates
- Cell-to-cell insulation barriers
- Busbar covers and terminal shields
- Enclosure insulation liners
- Electrical cabinet barriers and covers
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
Can you supply V0 rated material?
Yes, compounded from V0 resin so the rating runs through the thickness. Surface-treated flame retardancy is not appropriate for this application.
Do you machine parts to drawing or supply sheet only?
Both. For battery work most customers order finished parts — send DXF, DWG or STEP and we quote the machined component.
What documentation can you provide?
Tell us which standard your programme is assessed against and we will confirm what material certification and test data we can supply before you order.
