Crude oil

Expanded polystyrene (EPS), polypropylene (EPP) and piocelane are obtained from petroleum.

Styrol, Propylen and Polyolefine

Styrene (EPS), propylene (EPP) and polyolefins are produced in several stages. Piocelan is a hybrid, i.e. it consists of a combination of polystyrene and polyolefins.

Polytyrol, Polyproylen and Polyolefine

Polystyrene (C8H8)n, polypropylene and polyolefins (=plastic granules) are produced by polymerisation (a special chemical reaction). In the case of EPP, the blowing agent pentane is added, and

All belong to the group of thermoplastics.
