Epoxy resin board is a glass-fiber reinforced composite with high dielectric strength. This epoxy resin board withstands voltages up to 30 kV/mm without breakdown. The smooth surface of epoxy resin board prevents tracking and carbonization.

Electrical engineers specify epoxy resin board for busbar supports and terminal blocks. Epoxy resin board has a low moisture absorption rate of under 0.2%. The thermal class of epoxy resin board is typically Class F or H (155°C).

Epoxy resin board can be punched or machined into complex shapes. A yellow-green epoxy resin board indicates grounding applications. The flexural strength of epoxy resin board exceeds 350 MPa.

Flame retardancy of epoxy resin board meets UL94 V-0 standards. Epoxy resin board resists arc tracking with a CTI rating of 600+. The density of epoxy resin board is around 1.8 g/cm³.

Epoxy resin board is often used as an insulating barrier in power distribution. The thickness of epoxy resin board ranges from 0.5 mm to 50 mm. Laser cutting of epoxy resin board produces clean edges without delamination.

Epoxy resin board with aluminum backing serves as a heat sink. A UL recognized epoxy resin board simplifies product certification. Epoxy resin board ensures safe operation of electrical panels and switchgear.
