Product Description

3240 Epoxy Fiberglass Laminate Sheet Insulation Material

Epoxy resin is an organic macromolecule compound with two or more epoxy groups in the molecule. 3240 epoxy board is made of electrical glass cloth impregnated with epoxy resin, dried and hot pressed.

Epoxy board produced by domestic general materials, we can call it 3240 epoxy board, while the epoxy board produced by foreign production materials, we can call it imported insulation board, also called FR4 epoxy board.
3240 epoxy phenolic resin Fiberglass Cloth laminate, the glue used is epoxy resin with phenolic resin as curing agent. The temperature resistance is generally 155 degrees. It has good machinability, also very suitable for use in transformers and transformer oils. The density generally does not exceed the national standard: 1.9. But now there are many manufacturers in China, in order to save costs in the production process, adding in fillers, such as talcum powder. Its density is greatly increased. But it also greatly reduces its electrical performance, can only be applied to general insulation engineering.
