Which polymer is described as used for Jerry cans due to toughness and chemical resistance?

• A. PP
• B. LDPE
• C. UPVC
• D. HDPE

Answer: (D)

For a Jerry can you need a polymer that can take knocks and resist attack from fuels and solvents. High-density polyethylene provides a strong balance of toughness and chemical resistance, making it capable of withstanding impacts and maintaining its integrity when in contact with petrol and similar liquids. It’s rigid enough to hold its shape and stack or drop without cracking, yet still moldable enough for the familiar can design. Other polymers may be chemically resistant or lighter, but they don’t match HDPE’s combination of impact strength and hydrocarbon resistance, which is why HDPE is the common choice for Jerry cans.
