Plastic recyclates and plastics containing natural materials often have an unpleasant odor. This is not only a problem during production – it also severely limits the application range of the plastics concerned.

Plastic recyclates and plastics containing natural materials often have an unpleasant odor. This is not only a problem during production - it also severely limits the application range of the plastics concerned. However, an odor barrier layer with special additives can significantly reduce odor release.
- Fig. 1 : Production process for the sandwich component : two-component injection molding enables the production of the components. However, due to the molten state of the polymers, odorants migrate from the core into the skin during processing
- Fig. 2 : Sensory characterization of the odor release of the core material from PP recycled sandwich test specimens with an odor barrier layer (storage at 80 °C) : it is clear that odor reduction is highly dependent on the material and additive, its location and the amount used
- Fig. 3 : Odor release of sandwich test specimens, with PS core material made from fishing sector recyclates and odor barrier layer (storage at 80 °C): the best effect can be achieved with hydrophilic zeolite
- Fig. 4 : Characterization of odor release from PE lignin sandwich test specimens with odor barrier layer (storage at 80 °C) : hydrophilic zeolite is proving to be the additive of choice for reducing lignin odor |
