Polyethylene terephthalate (PET) can be recycled without leading to a gradual deterioration in quality. In contrast to other plastics (PP, PE, PS), PET is used without fillers – additives only get into the plastic matrix for colouring.
To be recyclable, however, it is necessary to remove all foreign components (e.g. metal closures, labels, incorrect throws) from the shredded PET fraction. If the required raw material is not available in a clean form, the temperature control during the melting process can be endangered or the die of the extruder can clog.
The IFE magnetic technology product range offers a number of suitable technical processes for efficiently separating ferrous and non-ferrous contaminants. Convince yourself of how IFE devices can enrich your PET processing measures and help you to obtain well sorted and metal-free PET fractions.
