G-3


We work with G3 glass phenolic laminates. G3 is a high-performance glass phenolic known for its high moisture resistance, resistance to melting, and integrity under continuous loads. Learn more on how we use glass phenolic laminates below.

What is G3 Glass Phenolic Laminate?

G3 is a phenolic made from woven glass fabric with high-temperature binding resin made up of formaldehyde and phenol. It undergoes a process of heat and high pressure, producing high strength and durability.

Glass phenolic laminates offer many notable benefits: excellent compressive, flexural, and impact strength; high creep resistance; and maintains integrity under continuous loads.

G3 properties include:

Tensile Strength — 42,000 psi
Comprehensive Strength — 76,000 psi
Flexural Strength - LW - A 0.125” — 55,000 psi
Specific Gravity — 1.85
Bond Strength — 1,500 psi
Shear Strength — 18,000 psi
Hardness - Mohs Scale — 110
Flammability Rating — 94HB
Izod Impact Strength at 49°C - LW — 12.00
Thermal Expansion Coefficient in Degrees Celsius (x10^-5) — 1.00
Maximum Operating Temperature — 284° Fahrenheit
