Edistir R 850E Polimeri Europa Polystyrene, High Impact

Product Description

Super high impact polystyrene with good heat resistance.

Designed for sheet extrusion and thermoforming of deep drawn containers even diluted with high percentage of GP. Suitable for general injection molding of tough medium-walled articles.

Designation: Thermoplastics ISO 2897-PS-I,G,093-03-10-18

Typical uses are thermoformed food packaging as disposable tumblers, flatwares, yogurt cups, lids. Injection molding of technical items, shoe heels, reels.

R 850E is certified UL94 HB "all colors" at 1.5 mm (UL file E83071).

This grade in natural version complies by composition with the requirements set by the main Regulations for plastic materials intended for food contact (included the EEC Directive 2002/72/CE and following amendments).
