But have you ever stopped to ask: what exactly is PVC? What does the name stand for? Why is it used so widely in conduit systems? And how does it compare with other materials like metal or HDPE?

In this post, we’ll answer the question above in detail. Whether you’re an electrical engineer, a contractor, or someone sourcing materials for a project, this guide will give you a clear understanding of PVC and PVC conduit.

Let’s start with the basics.

2. What Does PVC Stand For?

PVC stands for Polyvinyl Chloride—a name that sounds complex but breaks down easily when you look at its parts:

“Poly” means “many”, “Vinyl” refers to the vinyl group (–CH=CH2), a key chemical structure, “Chloride” comes from chlorine, one of the two raw materials used to make it.

Put it all together, and Polyvinyl Chloride simply means “many vinyl chloride molecules joined together.” This structure gives PVC its strength and durability.

Polyvinyl chloride is one of the most widely used thermoplastic polymers in the world. It can be softened and reshaped when heated—then hardened again when cooled. That makes it perfect for manufacturing pipes, conduits, and fittings of all sizes and shapes.
