HIPS is described as which of the following properties?

HIPS is described as which of the following properties?

• A. Hard, rigid, tough e.g. yoghurt pot
• B. Soft and flexible
• C. Transparent and heat resistant
• D. Low impact and poor chemical resistance

Answer: (A)

High‑impact polystyrene (HIPS) is a toughened form of polystyrene designed to absorb shocks while staying stiff. That combination gives a material that is hard and rigid, yet resistant to cracking when dropped or handled, which is why packaging like yoghurt pots is often made from it. It isn’t soft and flexible, so that description wouldn’t fit. It isn’t typically transparent; the rubbery modifier used to boost toughness makes HIPS more opaque or hazy, not clear. And its main draw isn’t low impact or poor chemical resistance—it's specifically chosen for high impact resistance and good overall toughness, with acceptable chemical behavior for many food‑contact uses.
