B38 Epoxy Glass Laminate

B38 epoxy glass laminate features a brominated epoxy resin formulation that provides V0 self-extinguishing and flame-retardant qualities. Its strong electrical insulation and mechanical strength make it ideal for electronic and electromechanical parts that may come into contact with flames.

Henry Gallacher can also produce custom B38 components through our in-house machining capabilities, including CNC milling, routing, turning, and drilling. For further details and examples of our precision work, please visit our machining service page.

B38 complies with the BS EN 60893 Standard: 3-2-EPGC202.
