Depending on the application, PP sheets must be filled with some filler, such as talc, to improve their physical properties or to reduce costs. In conventional process methods, PP must be mixed with the filler and then pelletized.Twin-screw direct extrusion technology combines masterbatch preparation and die extrusion. The in-line compounding nature allows for more flexible formulation changes than ever before and does not require masterbatch preparation.
