The viscoLAB provides the customers a variety of material testing services.
By heating up PET flake samples discoloration of its contaminants is achieved. Impurities like PVC, glue, polyolefins etc. can be optically detected and quantified.
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.
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.
Detection and quantification of the typical rPET substances Acetaldehyde (AA) and Limonene. A report including the chromatogram is provided.
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.
