Introduction to the composition of epoxy resin in epoxy resin board

Epoxy board is also called insulation board, epoxy board, 3240 epoxy board, which is made of glass fiber cloth bonded with epoxy resin and heated and pressurized. It has high mechanical properties at medium temperature and stable electrical performance at high temperatures. It is suitable for high-insulation structural parts for machinery, electrical appliances and electronics, with high mechanical and dielectric properties, good heat resistance and moisture resistance.

Epoxy resin board Epoxy resin generally refers to organic polymer compounds containing two or more epoxy groups in the molecule. Except for a few, their relative molecular mass is not high. The molecular structure of epoxy resin is characterized by the active epoxy group in the molecular chain. The epoxy group can be located at the end, middle or in a cyclic structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can undergo cross-linking reactions with various types of curing agents to form insoluble and infusible polymers with a three-way network structure.
