FR4 is a glass fiber reinforced epoxy resin laminate, the full name of which is Flame Retardant 4. It is made of glass fiber cloth impregnated with epoxy resin and formed by hot pressing. It has excellent insulation, mechanical strength and flame retardant properties.

Application

PCB circuit board substrate: This is the most widely used application of FR4
Motor insulation parts: motor slot wedges, partitions, etc
Transformer insulation brackets
Insulation partitions for high-voltage electrical equipment
Structural support parts in laser/mechanical equipment
Tooling fixtures/gauging tools/mold base plates
Flame-retardant structural panels for aviation and rail transportation
