What is PVC: use pro con

The second most widely used plastic after polyethylene, PVC has thus become one of the most essential materials in the field of construction. Small point on its characteristics, advantages and disadvantages.

Know and recognize PVC

Polyvinyl chloride or PVC is a thermoplastic polymer discovered for the first time during the 19th century following an accident. In 1835, the physicist Henri Victor R├ęgnault realized that after exposure to the sun, vinyl chloride bottles were transformed into a white solid. The first uses of PVC in the commercial field, on the other hand, did not begin until the 20th century.

Attempts initiated by Ivan Ostromislensky and Fritz Klatte, eminent Russian chemists, unfortunately ended in failure due to the difficulty of processing the product. It was not until 1926 that the company BF Goodrich and Waldo Semon managed to find a way to make the material more flexible and easier to work with. For this, they added additives to it. Thanks to this discovery, PVC could be used for commercial use.

The different uses of PVC

PVC is used according to its quality. Because you should know that there are four types in the industry. First, we find rigid PVC which is particularly appreciated in the manufacture of pipes (flows, gutters, waste water, etc.). This material is more stable and less harmful than lead, hence its great success in the creation of water drainage pipes.

He is also well known in the development of window dressings. There is also flexible PVC which has a shiny appearance and is mainly used in the creation of certain types of ceilings or floor coverings. Finally, there is PVC in the form of plasticized films which are used to make packaging. Also note, to finish, the expanded PVC very popular for making signs or advertisements at points of sale.

Focus on the advantages and disadvantages of PVC

PVC owes its great success to its countless advantages. Technical and technological developments have effectively improved the qualities of this material. Resistant to flames, the wear and tear of time and bad weather, it is also rot-proof and does not fear climatic variations. This material is light, malleable and 100% recyclable. It has a good insulation capacity, which is why it is appreciated in the field of carpentry. And above all, PVC is very affordable compared to other materials used in construction like aluminum or wood.

Be careful, this thermoplastic polymer still reveals certain limits. It is not biodegradable and may become toxic in the event of combustion or fire. When it is presented in the form of joinery, it tends to age badly because it is not very resistant to the ultraviolet rays of the sun. In addition, it has difficulty in resisting wear, especially if it is used as a floor covering. From an aesthetic point of view, its plastic appearance continues to predominate despite the decorative touches and finishes that can be added to it.
