Which of the following is NOT a listed use of PVC?

• A. Drainpipes
• B. Replacement windows
• C. Electrical insulation
• D. Ceramic tiles

Answer: (D)

PVC is a durable, cheap plastic that resists corrosion, is lightweight, and makes good electrical insulation. Drainpipes take advantage of its watertight joints and chemical resistance, so PVC pipes are a common choice for drainage. Window frames made from unplasticized PVC (uPVC) are weather-resistant and low-maintenance, which is why they’re popular as replacement windows. PVC coatings and insulation on electrical cables provide essential electrical insulation, keeping circuits safe and reducing energy loss.

Ceramic tiles come from ceramic materials like clay and glaze and are fired at high temperatures to harden. They’re inorganic and brittle, with heat resistance and surface hardness that plastics don’t match. Because of this, ceramic tiles aren’t a use of PVC.
