Based on the particular geometry of the RingExtruder, there are also clear advantages in degassing compared with other extruder systems. The following parameters, among others, are critical for good degassing:

  • High surface renewal rate thanks to double stripping of the screw surface per screw revolution
  • Large degassing or film surfaces on screws and inner cylinder wall
  • Small melt pools with an improved surface/volume ratio
  • Short diffusion paths
  • Large degassing cross-section
