What is Insulation G-11 Laminates, Tubes, Sheets and Fabricated Parts

G-11 is a high-performance glass epoxy laminate known for its exceptional mechanical and electrical properties. This material is widely used in various industries due to its ability to withstand high temperatures and humidity, making it suitable for demanding applications. Below is an overview of G-11 laminates, tubes, sheets, and fabricated parts.

G-11 is a thermosetting composite made from continuous filament glass cloth and epoxy resin. It is classified under the NEMA (National Electrical Manufacturers Association) standards, specifically designed for applications requiring high strength and electrical insulation. G-11 exhibits superior properties compared to G-10, particularly in terms of temperature resistance and mechanical strength at elevated temperatures.

Key Properties of G-11

Temperature Resistance: G-11 can operate at temperatures up to 180°C (356°F) for Class H and 150°C (302°F) for Class F.

Mechanical Strength: It retains significant structural integrity even at high temperatures, maintaining over half of its strength at elevated conditions.

Electrical Insulation: G-11 offers excellent dielectric strength and low moisture absorption, making it ideal for electrical applications.

Dimensional Stability: The material exhibits minimal warping or deformation, ensuring consistent performance in various environments.
