FR4 Epoxy Glass Fiber Parts

FR4 Epoxy Fiber Glass Sheet is a thermosetting laminate plastic.  FR4 Sheets are made of multiple layers of electrical fiberglass cloth impregnated with epoxy resin and heat pressed under high temperature and pressure. Both FR4 G10 Epoxy Fiberglass Rod or Sheet can be processed into parts.

G10 FR4 Glassfiber Sheet consists of two essential components: a thermoset epoxy resin matrix and glass fabric as reinforcement.

Epoxy Resin: The thermoset epoxy resin matrix forms the backbone of FR4 sheets, enabling load transfer to the fabric and providing chemical resistance and electrical insulation. Once cured, the resin offers excellent temperature resistance and withstands thermal stress.

Glass Fiber Reinforcement: Glass fiber fabric is embedded in the epoxy resin matrix, imparting mechanical stability to FR4 sheets. Due to their high tensile strength, shape retention, and insulating properties, glass fibers are the preferred choice. The primary type of glass fiber used in FR4 is E-glass (glass designed for electrical insulation); around 90% of reinforced glass fabrics are made with E-glass, which primarily consists of alumino-borosilicate.

The combination of epoxy resin and glass fabric gives FR4 sheets exceptional mechanical properties, with glass fibers bearing the load and resin shielding the fibers from environmental factors.

Because isolated G10 FR4 Epoxy Glass Fiber Parts come from FR4 Sheet , it have the same characteristics. We offer G10 FR4 Epoxy Glass Fiber Parts customized as drawing or sample.

FR4 Glassfiber Sheet for Electrical and Electronic Devices

Excellent Insulation Properties – FR4/G10 have high dielectric strength, allowing them to withstand high voltages. The controlled dielectric constant provides electrical insulation while allowing efficient electrostatic and electromagnetic field control.

Flame resistance – The flame retardant additives in FR4 and G10 give them excellent fire resistance meeting safety standards for electrical devices. FR4 can meet UL 94 V-0 flammability rating.

High mechanical strength – The fiberglass reinforcement in FR4 and G10 provides high strength and structural stability, enabling them to withstand stresses in electrical devices.

Moderate thermal conductivity – The thermal conductivity of FR4 and G10 is suitable for heat dissipation in electrical insulation uses.

Cost-effectiveness – FR4 and G10 are relatively low cost insulating materials.
