- Etronax is available in a large number of different qualities, which means that you can always find a type of material that meets your requirements.
- Certain types of Etronax have a self-lubricating effect, to mention just one of these qualities, and Etronax is generally characterized by being friction-reducing and extremely hard-wearing.
- The Quality of Cotton Defines the Properties
The quality of the cotton used for the production of composite materials with mechanical properties is not without importance. We have developed many different types of Etronax, which, amongst other things, are characterized by having different strength properties, and this is where the cotton quality is one of the factors that are crucial for the final result. The finer the cotton, the better the mechanical properties of the final composite material will be. Cotton quality is determined by thread density.
The cotton quality not only affects the strength properties of the material but also other important mechanical properties such as friction. The finer the cotton, the less friction is caused by the material, which is of great importance about, for example, ball-bearing cages.
- Advantages
- Composite based on cotton
- Good mechanical strength and wear properties
- Low friction and density
- Characteristics
- The material is distinguished by being strong and tough.
- Very low water absorption and lowest swelling in water.
- High chemical resistance, e.g. to SF6 gas.
- Suitable for high-voltage circuit breakers where SF6 gas is used as insulation medium.
