| Résumé : |
PET recyclates from different materials and colors pose big challenges for recyclers. Together with the University of Applied Sciences Magdeburg-Stendal, Germany, MultiPet GmbH is researching into injection-moldable blends that can be used to produce high-quality multi structured injection-molded parts from mixed PET. Only in the area of recycled clear PET samples the desired property profile was not achieved. |
| Note de contenu : |
- Which problems the processing of mixed pet fractions entails
- Desired technical functionality
- Sampling and characterization
- Expansion of the recyclables chain and processing
- After injecting the test rods, analysis and optimization follows
- In the practical test, the rpet blend with polycarbonate performs best
- Fig. 1 : Colorful mixture : the recycling of mixed fractions from bottles, blisters and trays remains a major challenge
- Fig. 2 : Bales of the specification mixed PET 70/30: during the material analysis the material was divided into the fractions other dimensionally stable PET packaging, trays with and without peeling film and blisters
- Fig. 3 : rPET blend compound and injected multi-purpose test rods
- Fig. 4 : Comparison of the intrinsic viscosity of PET blends and PET arnites
- Fig. 5 : Forward thinking : application examples for multi structured injection molded components made from mixed PET |
