Quality control

Aage Vestergaard Larsens ApS recycled material is subject to a comprehensive quality control, where raw material traceability is of crucial importance. Quality control is carried out before, during and after the production of the finished product. A sample of every produced unit is picked out for the final quality approval. All samples are archived for at least 3 years. The level of quality control in the context of subcontracting can be in agreement with the customer. Several analysis types are preformed during the conducting of the quality control, and this service can also be contracted out. Here, for example:   Mechanical properties:               Physical  properties : - Tensile properties                      - MFI, melt flow properties  - Impact strength                           - Viscosity (PET)   Thermal properties:                     - Density - DSC, thermal analysis               - Particle fraction - DSC, oxidative analysis             - Moist measurement Other equipment:                         chemical composition:               - Desiccant dryer                           - FT-IR analysis - Vacuum dryer                               - XRF analysis - Grinder - Laboratory extruder for   test compound production
