The GRAFE GROUP, has been a specialist in the black coloring of standard plastics for many years and has a broad portfolio of corresponding masterbatches. Based on these competencies, solutions are also being developed for an increasing number of engineering plastics and their corresponding applications, with the help of which brilliant black shades can be realized.
“In the PE/PP area, we offer a deep black for injection molding that produces a depth of color that can otherwise only be generated by soluble dyes in amorphous polymer structures. Upon customer request, the masterbatches can be combined to improve flowability and cycle time,” reports Danny Ludwig, Head of Product Management, Color & Functional Masterbatches, referring in particular to automotive applications.
“For injection molded parts in the engine compartment where PBT is used, we offer a solution that impresses with excellent homogenization at low dosage and can also be equipped with improved nucleation if desired,” Ludwig says. “In recent years, we have also increasingly established ourselves as a specialist for exterior components made of PMMA and are constantly developing these applications.” In addition to automotive, the expert also sees the construction sector as an important field of application.
For PA processing, GRAFE has a wide range of carbon blacks or nigrosine for black coloring. “The target group is injection molding applications, especially in the automotive sector, but also technically very demanding components in the construction sector. In addition, filigree and longer flow paths can be overcome more gently and components can be demolded and removed earlier.”
