High-Performance FR4 Fiberglass Epoxy Sheets – 0.5mm to 5mm Thickness – Custom Insulation Boards for PCB, CNC & Industrial Use

Looking for a high-strength, flame-retardant insulation material for your next project? Our FR4 Fiberglass Epoxy Sheets, available in thicknesses from 0.5mm (0.02") to 5mm (3/16"), are the perfect solution for a wide range of applications including PCB substrate fabrication, electrical insulation panels, high-temperature gaskets, and precision CNC machining. Made from glass fiber reinforced epoxy resin, these water green FR4 boards offer excellent mechanical properties, high dielectric strength, and outstanding dimensional stability. Whether you're building circuit boards, insulating industrial equipment, or creating custom electrical enclosures, our epoxy resin boards provide the reliable performance you need. Available in multiple sizes from 100×100mm (4" × 4") to 500×300mm (19.7" × 11.8"), these sheets are designed for both prototyping and bulk manufacturing.

Engineered for Durability, Precision, and Versatility

Our FR4 boards are manufactured from premium-grade fiberglass and epoxy resin, delivering exceptional resistance to moisture, chemicals, and heat. With a thermal rating up to 155°C (311°F) and flame-retardant properties (UL94 V-0), these boards are ideal for harsh and high-voltage environments. The epoxy core structure ensures rigidity and dimensional stability even under thermal or mechanical stress, making it ideal for electrical insulation sheets, custom CNC FR4 parts, and PCB mounting boards.
