PTI Calculator for PET Blends Is Offered as Free App

Published: November 09, 2011

HOLLAND, OH | Plastic Technologies Inc. (PTI) has launched a new free app that calculates the intrinsic viscosity (IV) of PET resin blends via a two-step process. The PET Blend Calculator is available on iPhone/iPad and Android platforms.

The company explains that virgin and recycled PET (rPET) have different IVs. As the use of rPET for packaging containers grows, the need for a quick way to calculate the blend’s IV increases. Reportedly, this hand-held device allows processors to easily get to the correct IV number in seconds, and the visual reference points are easy to plot and read. The company says it has the potential to save money by removing the guesswork from determining the correct final IV and minimizing the chance of producing underperforming products.
