Which of the following is a common use for PVC?

• A. Food packaging
• B. Pipes and electrical cables
• C. Medical implants
• D. Tires

Answer: (B)

PVC is a versatile thermoplastic that combines rigidity, chemical resistance, and good electrical insulation with low cost. In its unplasticized form it is rigid, strong, and resistant to water and many chemicals, which is perfect for making durable pipes that carry water or waste. It also serves as an excellent insulator for electrical cables, helping to protect and insulate conductors.

Other options don’t fit as well. For food packaging, polymers with different barrier properties and regulatory considerations (like PET or certain polyethylenes) are more common. For medical implants, biocompatibility and long-term stability inside the body are crucial, and implants are not typically made from PVC. Tires require highly elastic materials, and PVC’s rigidity makes it unsuitable for that use.

So the most common use is for pipes and electrical cables because of PVC’s rigidity, chemical resistance, and insulating properties.
