The CNT Production Process
as unique as the Product itself

To realize the production of such novel carbon nanotubes C-Polymers has developed a unique CL-CCVD process. Due to a great many deal of proprietary technology and process innovations the unique CNT offer a high structure and impact resistance which results in a high performance product designed especially for the high impact and high throughput requested by the plastics industry.

Both CNT processing and the compounding step is synergistically adjusted to meet perfectly the customer specification and implement the material into the client-processes to gain the most possible benefit over the entire value chain.

From Natural Gas to nano-Tube

Carbon nanotubes are commonly grown by means of catalytic chemical vapour deposition, also termed as CCVD. Within such process a catalytic active metal-nanoparticle is contacted with a carbon containing moiety existing in the gas-phase, usually a hydrocarbon, at red heat. On the metal surface the hydrocarbon is split into its elements C and H, which dissolve into the metal. However, as the catalyst particle gets saturated with C, tubular graphite is extruded from the particle at a rear crystallographic plane.

The such obtained whisker-like, graphitic structure is proven to enhance and/or create

• mechanical
• electric
• thermal

properties in composite materials, which is essential for host materials lacking such features at all.

Therefore, the opportunities for both plastics and thermosets, filled with CNTs are abundant. Very low loadings provide for antistatic and electrostatic dissipative applications, while leaving the desired properties of the polymer nearly unchanged.

Depending on the type of application, desired surface conductivity and mechanical properties of the final product a concentration of 3 to 8 wt.% CNT is recommended.
