PVC

What Is PVC Plastics

Polyvinyl chloride (PVC) is a popular thermoplastic that contains high levels of chlorine which can reach up to 57%. Carbon, which is derived from oil or gas is also used in its fabrication. It is an odorless and solid plastic that is white, brittle and can also be found on the market in the form of pellets or white powder. PVC resin is often supplied in the powder forms and its high resistance to oxidation and degradation make it possible to store the material for long periods. Some authors/activists that oppose the manufactures of PVC often refer to it as the "Poison Plastic" due to the toxic pollutants it might release. When plasticizes are added it becomes softer and more flexible.

Uses of PVC

PVC is predominant in the construction industry due to its low production cost, ease to mold and lightweight. It is used as a replacement for metal in many applications where corrosion can compromise functionality and escalate maintenance costs. Many of the world’s pipes are made from PVC and these are used in industrial and municipal applications. It is also used to make pipe fitting and pipe conduits. It does not have to be welded and can be connected with the use of joints, solvent cements and special glues--key points that highlight its installation flexibility. The material is also present in the electrical components such as: electrical insulation, wires and cable coatings.

In the health care industry it is used to make feeding tubes, blood bags, intravenous (IV) bags, parts of dialysis devices and many other items. This is only possible when phosphates are added to it. Phosphates are used as plasticizes to produce flexible grades of PVC (and other plastics), thus making it better suited for the aforementioned applications due to improved performance characteristics.

Common consumer products such as raincoats, plastic bags, toys, credit cards, hoses, doors and window frames and shower curtains are also made from PVC. This is not an exhaustive list of the many products that can be found around the household with PVC as its main constituent.
