Import Fr4 Epoxy Glass Cloth Laminated Sheet — Buy in Bulk from Supplier in China

The FR‑4 epoxy glass cloth laminated sheet is a composite panel built from non‑alkali, non‑wax cloth impregnated with epoxy resin. It delivers high mechanical strength and excellent electrical insulation, making it suitable for demanding industrial uses. The supplier offers a range of thicknesses and can adjust dimensions to match client drawings. All sheets are produced in China at the Jiujiang Honglida facility.

Typical industry grades such as TG‑150 provide a dielectric constant around 4.5 and a dielectric strength near 20 kV per mm, while moisture absorption stays below 0.10 %. The material resists chemicals, heat and humidity, which is why it is widely used for printed‑circuit‑board substrates, aerospace brackets and automotive electronic enclosures. Standard specifications include flexural strength above 350 MPa and an operating temperature window from - 55 °C to +150 °C. These characteristics align with the performance requirements of most high‑frequency and high‑voltage applications.

Electronics manufacturers, OEMs and system integrators commonly source this sheet for circuit‑board production and custom insulation parts. Trade terms are flexible, with minimum order quantities that can be adjusted and packaging that protects the sheets during transit. Importers should confirm the exact thickness, grade and Incoterms such as FOB or CIF directly with the supplier before placing an order.
