We work with G-5 glass melamine materials. Despite being replaced by G-9 materials, G-5 is still used in manufacturing parts for environmentally-specific industrial applications. Learn more on how we use G-5 for your project in our materials page below.

What is G-5?

G-5 is a woven glass fabric with a melamine resin coating. It offers superior hardness, flame-resistance, and electrical properties in both dry and humid environments.

Like other glass melamines, G-5 also offers impressive strength and arc resistance. It meets 94V-0 UL flammability requirements. It is a great material chosen for its high machinability, mechanical strength, and dimensional stability.

G-5 properties include:

Tensile Strength — 70,000
Flexural Strength - LW - A 0.125” — 55,000 psi
Specific Gravity — 1.90
Bond Strength — 1,900 psi
Shear Strength — 18,000 psi
Hardness - Mohs Scale — 115
Flammability Rating — 94V-0
Water Absorption (24 hours) — 0.60
Izod Impact Strength at 49°C - LW — 12.50
Thermal Expansion Coefficient in Degrees Celsius (x10^-5) — 1.50
Maximum Operating Temperature — 284° Fahrenheit

What forms of G-5 are available?

G-5 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.
