3240 epoxy sheets under GB/T 1303-2009 standard can be used for the insulation and encapsulation of lithium-ion batteries.

The series of epoxy sheets not only can meet the insulating requirements of your products but also has various colors for you to choose.

The corresponding types of the epoxy sheet under the National Electrical Manufacturers Association (NEMA) standard include FR-4 (temperature resistance 130°C, black, white, yellow, aqua green ones are available ), G10 (temperature resistance 155°C, color: aqua green), FR-5 (temperature resistance 155°C, color option: yellow-brown and dark green) and G11 (temperature resistance 180°C, yellow), as well as ordinary epoxy sheets (temperature resistance 130°C, color: yellow).

The difference between G10 and G11 is that the fiberglass content is 10% and 11% respectively.

Therefore, for those who require flame retardant performance, FR-4 and FR-5 can be the best choice.
