Versalis Edistir® PD ICE S 900 High Impact Polystyrene - Very High ESCR  (discontinued **)
Categories: Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Impact Grade, Glass Filled

Material Notes: Very high environmental stress cracking resistant (VH ESCR) HIPS.

ICE S 900 exhibits high toughness and excellent chemical resistance to oils, fats and chemical agents, and in particular to cyclopentane. Suitable for extrusion / thermoforming and injection molding.

Applications: Designed for inner liners and frames for refrigerators where cyclopentane is used as blowing agent for insulating polyurethane foams. ICE S 900 significantly improves the wall thickness distribution in thermoforming and allows to optimize the thickness of the original extruded sheet.
