Regular PVC (polyvinyl chloride) is a common, strong but lightweight plastic used in construction. It is made softer and more flexible by the addition ofplasticizers. If no plasticizers are added, it is known as UPVC (unplasticized polyvinyl chloride), rigid PVC, or vinyl siding in the U.S.
As a flexible plastic, PVC is used to produce a wide variety of piping. Larger PVC pipes are often used in plumbing to distribute non-potable water. PVC piping can also be used to insulate electrical cables.
uPVC is used as a replacement for wood in construction, such as in double glazed window frames and window sills and in what is known as vinyl siding in the U.S. It is a versatile material that can be manufacturered in many colors or made to look like other materials (e.g., wood). uPVC is also used instead of cast iron for certain types of heavy-duty plumbing and draining.
PVC is used as a replacement for copper and aluminum pipes and is used in waste lines, irrigation systems and pool circulation systems. It is easy to cut into smaller pieces and can be fastened with glue, making it a good alternative to metal.
uPVC is used for the majority of plastic pipes in the world, as it is incredibly resistant to chemical erosion and has smoother inner walls that help to encourage water flow. It also functions well in a wide range of temperatures and operating pressures. It is incredibly strong, stiff and cost-effective, and so is often used for sewage lines and exterior drainage pipes. Even so, uPVC piping is much less common in the U.S., where PVC piping is preferred.
Neither PVC nor uPVC is used to transmit drinking water. cPVC (chlorinated polyvinyl chloride) is used instead.
PVC is not used for window frames, although some manufacturers may use “PVC” to refer to their uPVC windows. Instead, uPVC is used for window frames, as it does not decompose and is weather-resistant.
uPVC will not change shape under normal weather conditions, but it can be reshaped at very high temperatures. uPVC windows are more energy-efficient than those with wooden or metal frames. Moreover, uPVC can also be used for door frames and conservatories.
Small and slender PVC pipes are sometimes found in medical equipment. PVC is also used in leather-like or waterproof clothing materials, vinyl flooring, shoes, toys, car interiors and car cables, shower curtains, and numerous other plastic products.
Because uPVC has fewer health concerns associated with it, it is found in medical and dental pieces. For example, uPVC is sometimes used for dental retainers.
