Product Description
General purpose polystyrene with very high flow and high heat resistance.

Special grade for direct gassing extrusion of heavy gage insulating boards (XPS) foamed by blowing agents alternative to CFC and HCFC.
Low viscosity process-aid and modifier for compounding.

Designation: Thermoplastics ISO 1622-PS,E,105-20

XPS insulation panels with improved environmental compatibility. Carrier for masterbatch. Modifier for thermoplastic elastomers and rubbers (shoe soles, cable extrusion-coating).

N 2982 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 2002/72/CE and subsequent amendments).
