Features & Benefits
- Materials Features
- Product Highlights
- Incredibly strong and retains its high mechanical strength even at high temperatures.
- This material thus has high thermal stability, and some types of G-Etronax can be used at up to 210°C.
- Certain selected qualities are also fire-retardant, which is why just the thermal properties alone make G-Etronax a highly versatile material.
- Extremely good electrical insulation properties
- Low water absorption
- High machinability
- Specially Developed Resins Result in Unique Properties
G-Etronax is produced from a base of either glass tissue or glass mats combined with one of our resins specially developed to meet the high requirements for electrotechnical and mechanical properties.
It is the resin that defines the final properties of the material, and the glass acts as a reinforcement of the resin. For G-Etronax we use various resins, all of which determine the properties of the composite material, such as:
- Strength
- Electrical properties
- Thermal insulation properties
- Advantages
- Composite based on glass
- Our absolute strongest materials
- Outstanding electrical insulation properties
- Characteristics
- Thermal class H insulation material.
- High chemical resistance.
- Particularly good and durable strength properties and insulation values, even at high application temperatures.
- Radiation-proof.
