What is G-7?
G-7 is a woven fiberglass laminate bound to a silicone resin. It is flame retardant with a low dissipation factor. Its properties ensure high arc and heat resistance, working well in both dry and humid environments.
Despite lacking the high tensile, dielectric, and flexural strength as epoxy resins, G-7 and other glass silicone materials have better strength in higher temperatures. Because of this, G-7 has a low-smoke evolution, meeting Class H insulation requirements.
Notable G-7 properties include:
Tensile Strength — 18,000 psi
Compressive Strength — 45,000 psi
Flexural Strength - LW - A 0.125” — 25,000 psi
Specific Gravity — 1.80
Bond Strength — 900 psi
Shear Strength — 17,000 psi
Hardness - Mohs Scale — 105
Flammability Rating — 94V-0
Water Absorption (24 hours) — 0.20
Izod Impact Strength at 49°C - LW — 6.50
Thermal Expansion Coefficient in Degrees Celsius (x10^-5) — 1.00
Maximum Operating Temperature — 428° Fahrenheit
What forms of G-7 are available?
G-7 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-7?
There are many benefits of this epoxy material, such as:
- Exceptional electrical resistance
- High stability in elevated temperatures
- Self-extinguishing
- Stable in high humidity
- Superior arc and heat resistance
