Versalis Edistir N 1840 Polystyrene
Categories: Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Molded, Unreinforced
Material Notes: General purpose polystyrene combining easy flow and medium heat. Edistir N 1840 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.

Designation: Thermoplastics ISO 1622-PS,G,085-12

Applications: Thermoformed disposable packaging and glossy sheets for industrial and fridge applications. Injection moulded beverage cups, point of sales, containers for foods and cosmetics, toys, housewares, medical articles (Petri dishes).

Edistir N 1840 is certified UL94 HB "all colors" at 1.5 mm (UL file E83071). This grade in its natural version complies by composition with the requirements set by the main Regulations for plastic materials intended for food contact (including the EEC Directive 90/128 and subsequent amendments).
