We work with G-10 epoxy laminate materials. It is very similar to FR-4, but G-10 is non FR glass epoxy. We’ll explain how G-10 is an ideal glass epoxy to use for your project.

What is G-10?

G-10 is a woven fiberglass laminate bound to an epoxy resin. It offers exceptional electrical properties, chemical resistance, and high strength. Since the 1950s, G-10 has been used predominantly in electrical applications like circuit boards.

10 is known for its high dielectric, tensile, and flexural strength, as well as its chemical resistance and thermal shock resistance. Some versions also offer flame resistance.

Notable G-10 properties include:

Tensile Strength — 40,000
Compressive Strength — 65,000
Flexural Strength - LW - A 0.125” — 75,000 psi
Specific Gravity — 1.80
Bond Strength — 2,200 psi
Shear Strength — 19,000 psi
Hardness - Mohs Scale — 110
Flammability Rating — 94HB
Water Absorption (24 hours) — 0.11
Izod Impact Strength at 49°C - LW — 14.00
Thermal Expansion Coefficient in Degrees Celsius (x10^-5) — 1.00
Maximum Operating Temperature — 284° Fahrenheit

What forms of G-10 are available?

G-10 is available in various shapes and sizes, including:

• Sheets
• Tubes
• Rods

All forms can be used in projects requiring various dimensions, lengths, diameters and thicknesses. If you have specific project requirements, please contact us for a consultation. We will coordinate with you on the best shape and size specifications for your project.

What are the benefits of G-10?

There are many benefits of this epoxy material, such as:

  • Radiation resistance
  • Chemical resistance
  • Thermal shock resistance
  • Dimensionally stable
  • High tensile strength
  • High dielectric strength
  • High flexural strength
  • High impact strength
  • Low dissipation factor
  • Low moisture absorption
  • Low cold creep
  • Applicable for certain cryogenic environments

How Does G-10 Compare to FR-4?

While similar to FR-4, G-10 is not flame retardant. These materials are not interchangeable, but you can often use FR-4 for applications requiring G-10. However, you should not use G-10 for applications requiring FR-4.
