It is a thermoplastic material designed for extrusion, thermoforming and injection moulding. Product has a form of cylindrical granules of diameter 2.5 to 6 mms. SYNTHOS PS GP 174 contains no internal lubricants.

APPLICATION
Injection moulding is used to produce parts with increased thermal resistance.
Production of XPS sheets and plates by means of direct extrusion and blowing.
It is suitable for blending with high-impact polystyrene (HIPS) and SBS copolymers to increase the thermal resistance of the product e.g. cups for hot drinks.
