Differences between PVC and CPVC

When selecting materials for piping systems, it’s crucial to understand the differences between PVC and CPVC, two popular options due to their versatile properties and applications. Although both share characteristics such as corrosion resistance and ease of installation, each has its own specific features that make it more suitable for certain projects.

In this blog, we will explore the key differences between PVC and CPVC in detail, from their composition and temperature resistance to their common applications and costs, to help you make an informed decision in your next construction or renovation project.

Feature	PVC	CPVC
Composition	Polyvinyl chloride	Chlorinated polyvinyl chloride
Maximum operating temperature	Approximately 60°C	Approximately 90°C
Corrosion resistance	Hight	Hight
Cost	Generally more economical	Generally more economical
Color	Gray or white	Beige, cream, or white
Flexibility	Moderate	Less flexible than PVC
Common applications	Cold water systems, drainage, and ventilation systems	Hot and cold water systems, industrial applications
Chemical resistance	Good, but less than CPVC	Excellent chemical resistance
Ease of installation	Yes, lightweight and easy to handle	Yes, but requires more precautions
Durability	Long life in suitable environments	Long life, especially in high-temperature applications
Lifespan	Long lifespan under normal conditions	Long lifespan, especially in high-temperature conditions

Similarities between PVC and CPVC

Both materials are resistant to corrosion and many chemicals.
Both are lightweight and relatively easy to install.
Both are used in piping systems for transporting liquids.
Both require specific adhesives for joining pipes and fittings.
