What is difference between PVC and uPVC pipes?

Polyvinyl chloride, commonly known as PVC, and unplasticized polyvinyl chloride, referred to as uPVC, are two types of plastic pipes that share similarities but also exhibit significant differences.

Here are the key distinctions between PVC Pipe and uPVC pipes:

1. • PVC (Polyvinyl Chloride): PVC Pipes are made from a plastic polymer composed of vinyl chloride monomers. These pipes may contain additives and plasticizers to enhance flexibility.
   • uPVC (Unplasticized Polyvinyl Chloride): uPVC pipes are also made from polyvinyl chloride, but the term "unplasticized" indicates that no plasticizers are added during the manufacturing process. This makes uPVC pipes more rigid and durable compared to PVC pipes.

2. Flexibility:

   • PVC: PVC pipes are generally more flexible due to the inclusion of plasticizers. This flexibility makes them suitable for applications where bending or curving is necessary.
   • uPVC: uPVC pipes are rigid and less flexible because they lack plasticizers. This rigidity makes them suitable for applications where strength and durability are critical.

3. Durability:

   • PVC: PVC pipes may be more susceptible to degradation over time, especially when exposed to sunlight (UV radiation) and certain chemicals. They may not be as durable in extreme conditions.
   • uPVC: uPVC pipes are known for their enhanced durability and resistance to sunlight and chemicals. They are more resilient in harsh environmental conditions, making them suitable for long-term applications.

4. Applications:

   • PVC: PVC pipes are commonly used in a variety of applications, including water supply, irrigation, drainage, and electrical conduits.
   • uPVC: uPVC pipes are often preferred for applications where rigidity and durability are crucial, such as underground water and sewer systems, industrial piping, and conduits.

5. Cost:

   • PVC: PVC pipes are generally more affordable than uPVC pipes, making them a cost-effective choice for certain applications.
   • uPVC: uPVC pipes may be slightly more expensive due to their enhanced durability and rigid composition.

Understanding the differences between PVC and uPVC is crucial when selecting pipes for specific applications, as each type has its own set of advantages and limitations. The choice between PVC and uPVC depends on factors such as flexibility requirements, environmental conditions, and the intended use of the pipes.
