viscotec viscolab roast test

Identification of contaminants

By heating up PET flake samples discoloration of its contaminants is achieved. Impurities like PVC, glue, polyolefins etc. can be optically detected and quantified.

viscotec viscolab instrinsic viscosity test

iV – intrinsic viscosity test

Pre-dried PET flakes and pellets are melted and pressed with a defined pressure through a defined die at a certain temperature. The flow speed determines the iV value.

viscotec viscolab surface moisture test

Surface moisture test

PET pellets or flakes are heated up to 160 °C so that the surface moisture vaporizes. The moisture content is calculated by relating the starting to the final weight of the sample.

viscotec viscolab gas chromatography

GC – gas chromatographic analysis

Detection and quantification of the typical rPET substances Acetaldehyde (AA) and Limonene. A report including the chromatogram is provided.

viscotec viscolab color test

Color test

Color measurement of rPET (amorphous PET after extrusion and/or crystalline PET after SSP) according to the L*a*b*- system. These three color values are decisive for the application.
