G10 FR4 represents the grade that is assigned to various types of thermosetting glass-reinforced epoxy laminate products that can take the form of sheets, printed circuit boards, rods and tubes. FR indicates the material is flame-retardant. Originally introduced in the 1950s, G10/FR4 features a UL 94 flammability classification of 94V-0. As such, G10/FR4 has remarkable anti-fire properties and is easily machined and die cut.

G10/FR4 is used in the electrical insulation of appliance PCBs and mechanical lines, G10 FR4 is created from electrical alkali-free glass cloth that has been impregnated with an epoxy resin under pressure and heat. It possesses high mechanical properties at medium humidity and good dielectric stability at high humidity. G10 FR4 has excellent dielectric strength, the best of all products that we offer. This makes it an excellent die-cut epoxy laminate for applications that require up to 0.005” thickness.

Examples of G10/FR4 Electrical Insulation Applications

Electrical insulators fulfill the role of restricting the flow of an electrical current. They typically provide support for materials that conduct electricity without allowing the current to pass through, while also providing protection for people, tools and objects that may come into contact with the conducting material. Common G10 FR4 applications include lighting fixtures, switches, timers, transformers, electrical controls and various electronic instruments and electrical devices.

Die-Cut G10/FR4 Insulators

Die cutting is one method commonly used to manufacture electrical insulators from G10 FR4 0.001” – 0.005” thick. Die cutting offers a fast, cost-effective way to cut this relatively thin material into the desired shape. Typical cutting methods include shear cutting, G10/FR4 material into the basic designated shape. Steel rule die cutting produces the desired result by punching the material and is the preferred choice for mass production projects on low thickness sheets. Laser cutting is the most technologically advanced technique and is ideally suited for complex, high-precision electrical insulator projects.

Machined G10/FR4 Insulators

G10/FR4 machining is also used to manufacture phenolic electrical insulation materials. Computer Numeric Control (CNC) machining makes use of computers that provide precise tooling control. It required the development of customized computer software that controls various aspects of the machining process such as feed rate, coordination, speed and location. This enables the manufacturing of highly complex shapes that typically cannot be produced via manual G10/FR4 machining methods. The process is also easily repeatable, which ensures remarkable consistency from one production batch to the next.

G Phenolics

Glass series of phenolics is a broad range of materials for specialized applications of electrical insulation. It is also known as Garolite ®. It is a glass woven fabric is impregnated with various resin binders to optimize unique characteristic of the material. It is available in sheet stock, rod, angle and U channel forms. It is available in a wide range of colors.

G5 / G9 - This material is fabricated from a glass woven cloth impregnated with a melamine resin binder. Melamine is the hardest of all laminates. It exhibits good dimensional stability, arc resistance and is resistant to caustics. G5 / G9 phenolics meet Mil-I-24768/1 GME requirements.

G7 - This material is fabricated from a glass woven cloth impregnated with a silicone resin binder. The silicone resin yields a laminate with excellent heat and arc resistance. It exhibits excellent dielectric properties under dry conditions and good dielectric properties under humid conditions. G7 phenolic meets Mil-I-24768/17 GSG requirements.

G10 / FR4 - This is the most versatile laminate available. The material is fabricated from a glass woven cloth impregnated with an epoxy resin binder. The epoxy resin yields a laminate with excellent mechanical properties. It exhibits good dielectric properties under dry and wet conditions. G10/FR4 phenolic meets Mil-I-24768/27 GEE-F requirements.

G11 / FR5 - This laminate is similar to G10/FR4 with a higher working temperature and improved mechanical strength at elevated temperatures. The material is fabricated from a glass woven cloth impregnated with an epoxy resin binder. The epoxy resin yields a laminate with excellent mechanical properties. It exhibits good dielectric properties under dry and wet conditions. G11/FR5 phenolic meets Mil-I-24768/28 GEB-F requirements.

GPO1 - This material is fabricated from a glass woven cloth impregnated with a polyester resin. This general purpose grade has good thermal electrical and mechanical properties. GPO-1 phenolic meets Mil-I-24768/4 GPO1 requirements.

GPO3 - This material is fabricated from a glass woven cloth impregnated with a polyester resin. Recognized by U.L. as having a 180 second arc-resistance and flammability class 94VO. Used in medium and high voltage switch-gear as barriers, supports, panels and high voltage TV components and insulators. GPO-3 phenolic meets Mil-I-24768/6 GPO3 requirements.
