GranaBlack Masterbatches

Not all black is the same!


We are familiar with different pigments and their qualities. 


Example of a customized black batch: 
An automotive application required the development of a masterbatch whose use laminates even a 50% glass fiber in the polyamide. The otherwise rough, gray-looking surface was successfully transformed into a glossy, black surface by GranaBack.
