As mentioned earlier, fluoropolymers can be used in many different areas, and the optimal fluoropolymer type and appropriate color masterbatch will depend on the part’s requirements. Understanding the part size and wall thickness allows a masterbatch to be designed with the appropriate pigment strength, particle size, and dispersibility. Color masterbatch formulations can produce opaque colors or can be developed with the appropriate pigment particle size and loading to enable translucent colors.
