Is PVC resistant to corrosion?

• A. True
• B. False
• C. It depends on the PVC type
• D. Only for non-medical environments

Answer: (A)

PVC's corrosion resistance comes from being a stable plastic polymer that doesn't rust or corrode like metals. Its surface is inert and resists attack by water, many acids, bases, and salts, which is why PVC is widely used for pipes, fittings, and chemical containment. In standard conditions, this makes it resistant to corrosion; there are formulations with different heat or chemical resistances, but the general property holds for typical PVC. So the statement is true.
