There are several types of glass epoxy sheets in the industry, such as G10, G11, FR4, 3240, etc. Currently, the two main series used in the market are G10 and FR4. In 2022, FR4 sheets accounted for 55% and G10 accounted for 27% of our glass epoxy sheet production. We expect that these two series will reach a combined proportion of 90% in 2023.

G10 and FR4 glass epoxy sheets are made from glass fiber cloth and resin. The glass fiber cloth provides support and, when filled with resin, is shaped into sheets for convenient transportation and cutting. The finished G10 and FR4 glass epoxy sheets have excellent insulation and electrical resistance properties. Some customized products also have antistatic, corrosion-resistant, chemical-resistant, high-temperature-resistant, and aging-resistant properties. It can replace many traditional materials.

G10 and FR4 sheets are both insulation and antistatic materials, commonly used in electrical and electronic equipment such as circuit boards, transformers, and switches. Although electrical insulation is its main use, it is also widely used in the aerospace industry, such as for manufacturing aircraft and spacecraft components, such as structural components, insulation boards, and radar systems. It is also commonly used in the manufacture of printed circuit boards (PCBs), connectors, and other electronic components. It is also used in the manufacture of engine components such as valve covers, timing gears, and distribution covers. Special G10 and FR4 sheets are also used to manufacture high-strength plates, structural beams, and other building components.

In addition to the applications mentioned above, G10 and FR4 glass epoxy sheets can be cut, drilled, milled, and processed into various shapes to make various complex parts.

We are a factory that produces G10 and FR4 glass epoxy sheets, and we support customized processing services for various epoxy sheets. If you need to purchase FR4 sheets or have a requirement for CNC machining of sheets, please contact us. We can provide free A4 size samples.
