Glass Cloth Phenolic Resin Characteristics
Glass Cloth Phenolic Resin (G-3) is a woven glass fabric with high-temperature phenolic resin. It has excellent flexular, compressive and impact strength. It also offers excellent heat and creep resistance. This thermoset plastic should only be used in low-moisture applications.
Excellent flexural and impact strength- Superior creep and heat resistance
- Useful in low-moisture applications
Applications for G-3
- Relays
- Switches
- Test boards
- Panels
- Gaskets
