Description
Product Name: T-HIPS 7350ESCR
Product Description: 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.
Applications:
- Sheet extrusion
- Refrigerator inner liners and door panels
- Packaging for oily food and dairy products
