Difference Between uPVC and PVC

When it comes to PVC and uPVC, there is not a lot of difference. In fact, uPVC is a variant of PVC, a common lightweight plastic used for construction purposes. It is this property of strength in addition to its lightweight that makes PVC and uPVC so popular. Let’s take a look at some of the differences between PVC and uPVC.

Chemical differences

PVC stands for polyvinyl chloride. It is an industrial plastic that is used majorly in construction of pipes, cable insulations, toys, clothes, etc. It consists of both phthalates, BPA and plasticizers that make it softer and more pliable. On the other hand, uPVC stands for unplasticized polyvinyl chloride. This chemical compound is achieved by adding a few additives and stabilizers to PVC, such as metal salts and soaps. This imparts additional strength, toughness and rigidity to the compound, thus making it popular in the construction of frames and profiles for doors and windows. Many uPVC doors and windows manufacturers carry out this process of conversion by adding chemicals to molten PVC powder, and profiles are then created at an extrusion plant.

Differences in properties

PVC is a soft material which can be easily moulded into any shape and design, and remains soft and flexible even in its final form. Consequently, it is less durable than uPVC since it can be easily deformed. PVC pipes and wirings are the major applications of the material since PVC is a good insulator and chemically inert, thus aiding in safe transportation of non-portable water through pipes.
uPVC is much more rigid and versatile, and is used in construction of durable and secure door and window frames which were earlier constructed out of wood or metal. This rising popularity of uPVC is due to its insulating properties like heat and noise insulation. Also, uPVC requires very little maintenance, and can be easily installed and repaired.

When it comes to similarities, both plastics are highly resistant to external chemical processes, decomposing, oxidation, sunlight, etc. Both PVC and uPVC are quite cheap and easy to manufacture. Although neither of the plastics are biodegradable, uPVC has the distinct quality of being easily recyclable.

Which plastic is preferred in windows?

uPVC is the preferred material of choice when it comes to constructing energy-efficient and highly functional window and door frames. It is stronger, durable, more long-lasting, and highly weather resistant. uPVC does not rot, corrode, decompose, or undergo pitting or scaling, which makes it an ideal material to resist the wear and tear of the environment. The best uPVC windows manufacturers in India, such as AIS Windows, utilize state-of-the-art specialized glass types that combine with uPVC to provide not only aesthetic benefits but also functional benefits such as heat insulation, pollution insulation, noise cancellation, privacy, intruder resistance, etc.
