Raw Materials For Epoxy Board Insulating Materials Heat Resistance And Moisture Resistance

Epoxy board is also known as epoxy glass fiberboard, epoxy phenolic laminated glass cloth board. Epoxy resin is an organic macromolecule compound with two or more epoxy groups in the molecule. Except for a few, their relative molecular weight 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 ring structure of the molecular chain. Because of the active epoxy groups in the molecular structure, they can cross-link with various curing agents to form insoluble and immiscible polymers with three-way network structure.
The laminated products made of epoxy phenolic resin impregnated with special electronic cloth by hot pressing at high temperature and high pressure have high mechanical and dielectric properties, good insulation, heat resistance and moisture resistance, and good machinability. The colours are white, light green, yellow and black. FR-4 Epoxy Glass Cloth, insulation board, epoxy board, epoxy board, brominated epoxy board, FR-4, glass fiberboard, glass fiberboard, FR-4 reinforcing board, FPC reinforcing board, flexible circuit board reinforcing board, FR-4 epoxy board, flame retardant insulation board, FR-4 laminated board, epoxy board, FR-4 light board, FR-4 reinforcing board. - 4. Glass fibre board, epoxy glass cloth board, epoxy glass cloth laminate board, PCB bored cushion board. It has high mechanical and dielectric properties, good insulation, heat and moisture resistance, and good machinability. It has four colors: white, light green, yellow and black. It is widely used as insulating structural parts in motor and electrical equipment. It is also widely used in FPC reinforcing board, PCB drilling pad, glass fiber meson, potentiometer carbon film printed glass fiber board, precise planetary gear (wafer grinding), precise test board, insulating brace separator of electrical (electrical) equipment, insulating pad, transformer insulating board, motor insulating parts, grinding gear, electronic switch insulation.
