Versalis Edistir® N 3380 General Purpose Polystyrene
Categories:	Polymer; Thermoplastic; Polystyrene (PS)
Material Notes:	High molecular weight general purpose polystyrene combining high heat resistance and good mechanical strength. N 3380 belongs to the third generation of Edistir® GPPS. Suitable for direct gassing extrusion, biaxial oriented film and sheet, glass clear sheet and panels. Also used in injection molding of medium wall-thickness transparent parts. Thanks to N 3380, injected items will be brighter and neutral colored in line with more sophisticated market needs. The new color will not be noticeable in covered applications. Applications: Suitable for foamed packaging trays, clear panels for shower cubicles, insulation boards (XPS), OPS for labels and packaging, clear molded fridge components, petri dishes and technical parts.
