Product: T-HIPS 7240
Description: T-HIPS 7240 is a very high-impact polystyrene for the extrusion industry. This grade has been designed to be diluted with crystal polystyrene. The good melt strength of this grade makes it particularly suited for deep-draw thermoforming. T-HIPS 7240 is available in white color.
Applications:
- Dairy sheet, cups, trays, egg boxes, general packaging, coextrusion with GPPS at industrial sheets.
