Advantages of the ZSK MEGAcompounders in devolatilization service:
-Large degassing surfaces, effective even beyond the area of the degassing opening through the axially open screw system
-Degassing in several separate vacuum stages by melt seals in the screws
-High degassing coefficient through high screw speed with simultaneous gentle treatment of the material
-Addition of stripping media with homoge-neous incorporation into the melt
-Pulsation-free material feed and conveying, even with partially filled screws
-Reliable removal of vapor streams
