EPS Process
Expandable Polystyrene is a thermoplastic material in spherical bead shape, which contains Pentane as expansion agent, and is obtained in result of polymerization of Styrene.
The transformation process of expandable Polystyrene is realized with water vapor and the volume of the beads reaches 40 times of its original volume within less of one minute.
Expandable Polystyrene (EPS) Conversion Process
There are five production phases in the “Expanded Polystyrene” process realized using the Eurocell & Ravacell raw material:
Pre-expansion
Every one of the Polystyrene granules are expanding being exposed by free exposure to steam in order to constitute larger grains consisting from series of cells, which are not interconnected.
Conditioning
After the expansion, the beads are still containing condensed vapor and pentane gas in small quantities. After being cooled down, air replaces partially the other components and diffuses gradually into the pores.
Molding
These beads are molded in order to constituted boards, blocks or optional products. The mold serves to shape and retain the pre-foam, steam is reused in order to promote the expansion. During the molding steam causes the fusion of every single bead with its neighbors, thus a homogenous product is constituted.
Shaping
After a short cooling period, the molded block is taken off the machine and after an additional conditioning, they can be cut and shaped in the desire shape using a hot wire element or other appropriate technique
Post-Production-Processing
Finished product can be laminated with other coverings i.e. foils, plastics, roof felts, fiber-board or roof or wall or wall cladding materials.
