With our AF-Carbon® product range, we offer customers a comprehensive portfolio of technically sophisticated carbon black concentrates. Different carbon blacks are used for different applications in various industries, most commonly black masterbatch and carbon concentrate. Our eco-friendly, high-quality production facilities offer a formidable infrastructure for the manufacturing of carbon black concentrates. We also develop technically sophisticated batches on different thermoplastic carrier materials.
One important quality factor is dispersion. By producing to extremely high standards, we are able to cater to sector-specific requirements such as minimised agglomerate measurements. Together with our test laboratory, we carry out controls and tests for many different technical aspects in order to fulfil your individual requirements.
The Quality Is in the Detail
This is very true for carbon black concentrates. One product may look like another at first glance, but the subtle differences are hidden just beneath the surface. Our standard portfolio includes some 30 products, all of which vary in their suitability for use in a broad range of applications and also in the carrier and grade of carbon black. The AF-Carbon® range of products provides a comprehensive portfolio of technically sophisticated carbon black concentrates. Here you can find an abstract of our AF-Carbon® products and their suitability.
Any Color, as Long as It Is Black
Carbon black reaches its limits in some applications with the highest demands on technical and / or aesthetic aspects. Soluble dyes clearly prove to be advantageous here. They are not coated with the polyamide matrix as in case of pigment particles, they dye them directly.
This exception is our nigrosine black-based masterbatches. Wherever the influence of the carbon black on the recrystallization behavior of certain polymers is relevant, e.g. For PA6 / PA66 blow molding applications, these types of products are used.
Our soot-free recipe of AF Carbon® (AF-Carbon® PA 950509 black) similarly improves the processing properties. Nigrosine is soluble as a dye in polyamide and thus has no nucleating properties. The special formulation makes open a vast expanse of the processing window. This is achieved by reducing the recrystallisation temperature from 12-17 Kelvin, both in PA 6 and PA 6.6.
In addition to improved shape imaging, gas or water injection pressure applications (GID, WID) and foam injection molding also achieve significantly improved results.
