- The Best Carbon Fiber for Each Application
Our carbon fibers are available coated with various sizings and in different staple lengths to ensure consistently optimum fiber dispersion whatever the application, e.g. for thermoplas- tics, thermosets or aqueous processes.
For the production of compounds, we supply carbon fibers with special sizings. These are perfectly matched to the processing temperatures and bonding characteristics of the different thermoplastics. With our different SIGRAFIL materials, you can choose the specific carbon fiber property that you need.
Whether you are using carbon fibers as a reinforcing material or a filler, their properties can be transferred to your compounds and composites and ultimately to the end products. This opens up many different possibilities for you.

Technical Details & Test Data
- Relative Properties of Chopped Carbon Fibers in Poly Carbonate
In the production of compounds, chopped carbon fibers are traditionally used as a filler material. By varying fiber staple length and loading. it is possible to control how strongly a particular carbon fiber property is expressed in the compound. With higher fiber loading. there is a corresponding decrease in electrical resistivity and hence an increase in conductivity. Higher conductivity also results in better electromagnetic shielding. Similar behavior can be seen in the mechanical properties of our carbon fibers. With higher filler loading in the compound, stiffness and strength are increased, although the rise in stiffness is far greater.
