3240 Epoxy Fiberglass Insulation Sheet, High Temperature Resistant Board
Introducing the 3240 Epoxy Fiberglass Insulation Sheet — a compact, high-temperature resistant board designed to safeguard LiFePO4 battery packs in DIY projects. Built from fiberglass with an epoxy composition, this insulation sheet stays lightweight while delivering dependable thermal protection. Sized at 300mm by 200mm with a slim 0.5mm thickness, it’s easy to cut to the exact shape and size you need for tight enclosures or custom battery configurations. The sheet comes in a distinctive yellow color, adding a clear visual cue for insulation placement in your build.
Designed specifically for LiFePO4 battery packs ranging from 90Ah to 320Ah (examples include 3.2V variants), this board provides a practical insulation layer that helps manage heat during charging and discharging. It’s ideal for DIY battery pack assemblies where space is at a premium and a lightweight, flexible insulating solution is required. Please note that minor cosmetic defects may appear on the product, but these do not affect insulation performance. If appearance is a priority, please consider this before ordering. All electronic and mechanical equipment sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
