SYNTHOS PS GP 137 is general purpose polystyrene (GPPS) with excellent optical properties, gloss and very easy flow - good processability. It is a thermoplastic material designed for injection moulding and extrusion. Product has a form of cylindrical granules of diameter 2.5 to 6 mms.

APPLICATION
Injection moulding is used to produce e.g. cups for the food industry, medical devices, caps, casings, drawing templates.
In the extrusion of plates and sheets with glossy surface is used most often as a co-extrusion material (glossy top layer).
The composition of the polymer meets the requirements of the Health and can therefore be used for the production of articles coming into contact with food.
