G-7 Laminate
Overview
What is the Material: G-7 Laminate is a thermoset material, which consists of glass fabric filled with silicone resin.
Key Material Features: This material is beneficial in applications where mechanical and electrical properties must be retained in environments of high heat and humidity.
Other Considerations: At low temperatures the silicone resin is not as strong as epoxies and other phenolics.
