Product Details HIPS (High Impact Polystyrene), also known as PS (Polystyrene), is an amorphous thermoplastic material, used in lower heat applications. It is categorized as a standard material, and offers ease of processing, high impact strength, and stiffness.wer than HIPS, better than PMMA, PC, etc., good flexibility. Properties Impact strength: HIPS is more impact resistant than homopolymer PS. Rigidity: HIPS is stiff and has good dimensional stability. Ease of processing: HIPS is easy to fabricate, machine, paint, and glue. Affordability: HIPS is inexpensive to produce. Heat resistance: HIPS is suitable for lower heat applications. Applications Packaging: HIPS is often used in packaging applications because of its impact strength and rigidity. Consumer goods: HIPS is used in the manufacturing of many consumer goods. Food processing: Natural HIPS can be used in food processing applications. Prototypes: HIPS is a popular choice for producing pre-production prototypes.
