Diamat material preparation is gentle and highly efficient

Moisture in plastic pellets or PET-flakes can have a negative influence on the quality of your plastics extrusion. This is not only true for water on the surface of granules, but also for hygroscopic polymers like PET that bond with moisture on a molecular level. Our plastic dryers can solve this problem: 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 plastic resin will be re-crystallised and dried to a residual moisture content of less than 50ppm.

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. Or you can just contact us for an individual solution.

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

Extrudable plastics

Our plastic extruder machines can mix components to the gram and melt them at exactly the right temperature.

Therefore our plastic extruders are able to extrude a large variety of plastics including:

  • polypropylene (PP)
  • polyethylene (PE, also known as polyethene or polymethylene)
  • high-density polyethylene (PE-HD)
  • polyurethane (PU or PUR)
  • thermoplastic polyurethane (TUR)
  • polystyrene (PS)
  • acrylonitrile butadiene styrene (ABS)
  • ethylene vinyl alcohol (EVOH)

and various polyesters like polyethylene terephthalate (PET – including recycled flakes) or amorphous PET (A-PET).

Other components from diamat

Various plastic pellets and bottle flakes from white big bags are conveyed into an extruder.
