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.
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.
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.
GC – gas chromatographic analysis
Detection and quantification of the typical rPET substances Acetaldehyde (AA) and Limonene. A report including the chromatogram is provided.
iV – intrinsic viscosity test
Laboratory procedure for iV measurement of PET. The right procedure is crucial especially when testing iV of post-consumer bottle flakes to ensure precise and valuable results. viscotec offers basic and advanced training to our customers in order ensure precise measurement and quality control.
PET sheet shredder cuts quality samples
rPET sheet is cut into quality samples in preparation for the iV measurement procedure. The PET sheet shredder is a mobile, simple and space-saving device that precisely shreds sheet samples. Dust-free and efficient.
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.
