POLYCASA® PS stands for extruded crystal polystyrene sheets which provide solutions for many indoor applications. Thanks to the extrusion process, alongside the clear transparent standard products (with or without anti-reflective), there are also a variety of colours and patterns on offer.

POLYCASA® PS sheets are not only used for a number of different purposes in the field of visual communication, e.g. as signage for advertising campaigns, as POS / POP displays or as glazing for picture frames but also for sanitary ware (e.g. shower cabins).

Recycled content

The current production of our POLYCASA® PS sheets already contains a proportion of recycled polystyrene which is mainly recovered from our own production waste. After being sorted into individual types, the material is returned to the production process in the form of regrind. We aim to continue increasing the proportion of recycled regrind in the sheets in the future.

All raw materials used in our POLYCASA® PS sheets comply with the requirements in the current version of the European Union's Chemicals Regulation (REACH). In particular, POLYCASA® PS sheets are free of any of the substances listed in the current version of the ECHA Candidate List of Substances of Very High Concern (SVHC).

Product life cycle

Our POLYCASA® PS family is made of polystyrene, a durable thermoplastic polymer which is suited to interior applications, for instance: signage, displays or glazing in picture frames, and also for sanitary ware such as shower cabins. The version featuring UV-protection ensures sheets remain colour constant for many years in interior applications.

POLYCASA® PS sheets can be recycled and then reused without significant impact on the material properties. Styrene based polymers can even be recycled numerous times.
