Epoxy board, also known as epoxy laminated sheet, is a high-performance insulation material widely used in electrical, mechanical, and industrial applications. It is manufactured by impregnating glass fiber cloth with epoxy resin and curing it under high temperature and pressure, resulting in a rigid, durable, and dimensionally stable material.
Thanks to its excellent electrical insulation properties, epoxy board is commonly applied in power distribution equipment, electrical panels, transformers, and insulating structural components. It provides reliable insulation even under high voltage and harsh operating conditions.
Key Properties of Epoxy Board
Epoxy board offers a balanced combination of electrical, mechanical, and thermal performance:
-
Excellent electrical insulation
High dielectric strength and low water absorption ensure stable insulation performance. -
High mechanical strength
Good impact resistance, bending strength, and dimensional stability make it suitable for precision machining. -
Thermal resistance
Maintains performance under elevated temperatures, suitable for continuous industrial use. -
Chemical resistance
Resistant to oils, solvents, and most industrial chemicals. -
Good machinability
Can be CNC machined, drilled, milled, or cut into complex shapes according to drawings.
Common Applications
Epoxy boards are widely used across multiple industries, including:
-
Electrical insulation parts
-
Switchgear and control cabinets
