Polyvinyl chloride is commonly used as what?

Polyvinyl chloride (PVC) is a versatile synthetic plastic polymer that is extensively used in various applications due to its favorable properties. One of the key uses of PVC is indeed for piping, particularly in water supply systems. It is valued for its durability, resistance to corrosion, and low production cost. PVC pipes are widely employed in residential and commercial plumbing, drainage, and irrigation systems, making them essential for water distribution.

When considering insulation, while PVC can provide some insulating properties, it is not principally known or commonly utilized specifically as insulation material. Instead, materials like rubber or foam are typically preferred for thermal and electrical insulation due to their superior properties in those applications. Thus, while PVC can contribute to insulation in some contexts, it is not its primary function or widely recognized use.

Understanding the correct use of PVC highlights its importance in infrastructure and construction, particularly in the context of reliable water supply systems.
