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 7350ESCR is a high-impact polystyrene grade with improved stress crack resistance compared to conventional high-impact polystyrene. It has excellent melt strength, making it suitable for deep-draw thermoforming. It offers good environmental stress crack resistance at low temperatures, ideal for applications in frozen packaging and oily food and dairy products.
T-HIPS 8350 is a high-impact polystyrene designed for extrusion sheets, offering improved ESCR compared to other high-impact polystyrene types like HIPS 7240. It provides excellent melt strength, making it ideal for deep-draw thermoforming. T-HIPS 8350 is suited for packaging applications that may involve stress cracking from fats, oils, or low temperatures, including products requiring contact with HCFC-expanded foam insulation.
