Message
High molecular weight general purpose polystyrene combining high heat resistance and good mechanical strength. N 3380 belongs to Edisitr® GPPS third generation.
Suitable for direct gassing extrusion, for biaxially oriented films and sheets, for glass clear sheets and panels.
Also used in injection moulding of medium-thickness wall transparent parts.
Thanks to N 3380, injected items will be more brilliant and neutral coloured in line with more sophisticated market needs.
The new colour will be not appreciable in covered applications.
Designation: Thermoplastics ISO 1622-PS,G,105-03.

Applications
Suitable for foamed packaging trays, clear panels for shower cabins, insulation boards (XPS), OPS for labels and packaging, moulded fridge clear components, Petri dishes and technical parts.
