EPS Plant process

EPS is a rigid foam insulation material produced from solid beads of polystyrene (with a diameter of 0,2 to 0,3 mm). Expansion is achieved by virtue of small amounts of pentane gas that is dissolved into the polystyrene base material during production.

The gas expands under the action of heat, applied as steam, to form perfectly closed cells of EPS. These cells occupy up to 50 times the volume of the original polystyrene bead. During the expansion process the EPS beads are moulded into blocks. EPS blocks can be cut into sheets or a variety of shapes to suit the application.
