General purpose polystyrene combining easy flow and medium heat. N 3840 belongs to Edistir® GPPS third generation. Edistir® N 3840 is suggested in extrusion for glossy capping of HIPS sheets and for blending with HIPS or clear SBS for stiffer thermoformable sheets. This grade exhibits excellent processability in injection moulding and it is recommended for complex and thin-wall parts and fast moulding cycles. Thanks to N 3840, injected items will be more brilliant and neutral coloured in line with more sophisticated market needs. Designation: Thermoplastics ISO 1622-PS,G,085-12. Thermoformed disposable packaging and glossy sheets for industrial and fridge applications. Injection of moulded beverage cups, containers for foods and cosmetics, toys, housewares, medical articles (Petri dishes). |
