Expandable polystyrene (EPS) is the raw material used in Plastro’s production process, it becomes over three stages in blocks or castings.
The three stages are:
The feedstock is heated in a special facility, with water vapor at temperatures between approx. 80 and 110 ° C. Depending on the temperature and time of exposure, the apparent density decreases from about 630 kg/m3 to about 10 kg/m3. For the manufacture of packaging and other castings, expanded polystyrene is typically between 18 and 45 kg/m3.
Pre-expansion process, the beads compact of the raw material are converted into cellular plastic beads with small closed cells.
2. Intermediate rest
Upon cooling newly expanded particles condenses the blowing agent and the water vapor in the cells, creating a vacuum which is necessary to compensate with the penetration of air by diffusion. Thus, the beads reach a greater mechanical stability and enhance its expandability, which is advantageous for the above transformation. This process takes place during sleep through the pre-expanded material in silos ventilated. While the beads are dried.
3. The final expansion
Cavity formed by the two half molds typically used in this process, pre-expanded material is filled through a pneumatic feeder. The mold walls are provided with nozzles (holes or slits) communicating the cavity with the vapor chamber. The energy required for the final expansion is provided in the form of water vapor.
