Minimizing PET degradation by using OmyaPET in compounding
The presence of moisture and some additives degrades polyethylene terephthalate (PET) during extrusion.
For this reason, masterbatch manufacturers have avoided the use of calcium carbonate in PET masterbatches and compounds.
Since the launch of OmyaPET, it has been possible to take advantage of the unique benefits that calcium carbonate offers polymer processors.
These include strengthening the product, reducing costs, increasing opacity and reducing the carbon footprint.
