Diamat material preparation is gentle and highly efficient

The perfectly premixed and bulk density optimised material is conveyed to the crystallisation via a screw conveyor. In our in-house developed crystallisation system, the material will be re-crystallised and dried to a residual moisture content of 50ppm.

The most important benefits of the diamat PET crystallisation dryer in summary:

  • Very low residence time
  • Very low buffer amounts
  • Very low residual moisture < 50 ppm
  • IV reduction max. approx. 0.02 percentage points
  • Very gently but highly efficient process
  • High energy efficiency, low energy consumption
  • Extremely high flexibility processability of a wide range of materials
  • Processability of a wide range of qualities
  • Processability of PE/PET composite materials
  • Excellent price/performance ratio
  • Operator simplicity
  • Mature and proven technology

The information and possibilities on the subject of A-PET extrusion are now so widely scattered and confusing that we have compiled additional information material.

We will be happy to send you our information brochure on request.
