Why Drying?

Moisture, the unseen enemy of plastic quality

Hygroscopic engineering plastics like PA, PC, PBT and PET absorb moisture from the air. Insufficiently dried material causes silver streaks, bubbles, strength loss and surface defects. The right dryer brings material fully dry before processing; with a closed loop and hot-air recovery it saves up to 40% energy.

  • Prevents silver streaks and bubble defects
  • Closed loop — stops moisture reabsorption
  • Up to 40% energy via hot-air recovery
