Key Characteristics of G-10

G-10 is a high-performance thermoset composite material, consisting of woven fiberglass cloth impregnated with an epoxy resin. 

This material is highly valued for its excellent strength-to-weight ratio, making it a versatile choice for a wide range of industrial and mechanical applications.

 

G-10 provides exceptional mechanical strength, maintaining its structural integrity under stress, and offers superior dimensional stability, even in challenging environments. It also has good resistance to wear and abrasion, making it a durable material in applications requiring toughness.

 

While G-10 is not inherently flame retardant like FR-4, it still performs well in high-temperature applications, withstanding continuous use temperatures up to 140°C (284°F). It also has low moisture absorption, which enhances its stability and performance in moist or humid conditions.

How It's Used: Applications of G-10:
