G-11 - Glass Epoxy
Key Characteristics of G-11
G-11 is a high-performance thermoset composite material made from woven glass fabric and epoxy resin.
The material is particularly prized for its exceptional electrical insulation properties, especially at elevated temperatures. G-11 can perform reliably in temperatures up to 180°C (356°F), making it ideal for high-temperature applications.
The material also exhibits excellent mechanical strength, maintaining its structural integrity even in challenging environments.
G-11 has low moisture absorption, which contributes to its dimensional stability, ensuring consistent performance in both dry and humid conditions.
Additionally, G-11 offers good chemical resistance, enabling its use in environments where exposure to harsh chemicals may occur. Like G-10, G-11 is flame-resistant, further enhancing its suitability for high-heat and fire-prone applications.
