For example, the heat and chemical resistance of a fluoropolymer will greatly influence the pigment selection process.
In contrast, rod extrusion would require very stable pigments due to the longer residence time in the extruder.
Understanding the part size and wall thickness allows a masterbatch to be designed with the appropriate pigment strength, particle size, and dispersibility.
