Business case of cabka
The goal of the Cabka business case is to add recycled PP into pallets showing electrostatic discharge (ESD) characteristics, keeping the ESD and required mechanical properties of the standard pallets. In this article, you can read about their work done.
The strategy followed to reach project objectives has been based on working firstly on a laboratory scale with specimens and plates as shown in the attached figure.
Once the desired results have been obtained in the laboratory with the specimens, the next step would be to scale up these results to the industrial level on pallets.
The mechanical and ESD properties obtained have been analysed and studied on these specimens and plates.
During this period has been worked in a laboratory scale with the plates and specimens making comparison between ESD material made with Virgin material and ESD recycle based material: results obtained to date are quite similar, at least as far as laboratory scale is concerned, as the ESD properties obtained with virgin material are in the same range level in terms of electrical conductivity to the properties obtained with recycled material (see attached graph).
The resistivity value obtained on the specimens corresponds to a dissipative grade, practically raising the conductive grade. Below is a scale on which the materials are classified according to the degree of electrical resistivity achieved.
(Some literatures consider a conductive material the one which has surface resistivity lower than 10 exp 5 Ohms/Sq)
Next steps currently being worked on, would be to replicate these results on a pallet, considering the different process conditions between obtaining the specimens and obtaining the pallets.
It should be noted that the pallets are subjected to a series of load tests under standard regulations.
Thus, materials developed based on recycled material not only have to achieve the ESD properties, but also must pass the corresponding mechanical tests to which the pallet is subjected.
