The PET dryerless extrusion is the ideal solution to reduce costs and increase process flexibility.

The PET dryerless extrusion process is the extrusion technology without drying with an integrated filtration unit advised to optimize the production costs without affecting process flexibility. This solution enables to overcome all typical issues related to PET flakes processing such as viscosity and bulk density irregularities, presence of pollutants, the formation of dust, etc. and resulting of significant advantage in the reduction of electric power consumption as well thanks to the possibility to avoid to dry the polymer.

Basic features

• optimized melt homogenization
• efficient melt decontamination
• lower polymer degradation
• maximum process flexibility with possibility to process either PET granules or PET flakes; mix of both is possible as well
• lower energy consumption with production costs saving
• equipment space reduction
• suitable for One-Step, Two-Step and Spunbond processes
