Description
Product Name: T-HIPS 8350
Product Description: 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.
Applications:
- Thermoforming
- Fridge doors and cabinet liners
- Packaging for fatty food sheets
