Different from fiberglass pultruded profiles, fiberglass epoxy resin sheet is made from chemically treated electrician non alkali fiberglass cloth as the backing material, epoxy resin as a binder to laminate formed by hot pressing under high temperature, high mechanical strength, electrical properties under high humidity stability.

Advantage of Fiberglass FR4/ G10 sheet

*High mechanical & electrical strength
*Excellent rigidity & dimensional stability
*Insulation, Good dielectric properties Easy to machine
*Tighter thickness tolerance Smooth and clean surface.
*Low water absorption
*Flame resistance
* High-Temperature resistance
*Flatness, Smooth surface
*Reinforced
Difference of different color
The epoxy glass cloth board is yellow, the material is epoxy resin, and the epoxy glass fiber board material is glass fiber, which is generally aqua green. Its temperature resistance is higher than that of the epoxy glass cloth board, and the insulation in all aspects is also better. For epoxy glass cloth board, the price is also higher. The basic properties of the two of them are the same, they are insulating, wear-resistant, high-voltage resistant, and corrosion-resistant.


Application of Fiberglass FR4/ G10 sheet
1. Motors and electrical equipment insulation parts,
2. Fpc reinforcement plate, Carbon film board,
3. RC hobby parts, UAV Film frame
4. Electrical insulation, Insulating structural parts in electrical & mechanical
equipment, such as generators, motors, transformers, terminal boards, PC boards, washers
5. more.
