PVC or Polyvinyl Chloride is one of the most popular thermoplastic polymers in the world. It’s is only a few plastics like PP and PET that surpass it in usage. Before plasticizers are added to it, it is a very brittle and white plastic. It was first synthesized in 1872 making it one of the first plastics in the world. In the 1920s, it was commonly produced by B.F. Goodrich Company. Most plastics that are common today were first synthesized and used in the 1940s and 1950s. PVC is commonly used in the construction industry but it also has applications for clothing, healthcare applications and signs.
There are two general forms of PVC. One is flexible plastic while the other is un-plasticized or rigid polymer (uPVC or RPVC). Regular, flexible or plasticized PVC is softer and can be bent more easily than uPVC because of the addition of plasticizers like phthalates e.g. DINP. Rigid PVC pipes can be used for plumbing pipes and it can be used for siding or vinyl. Flexible PVC can be used for flooring in schools, homes and hospitals to create a sterile environment. It is also used as insulation in electric wires and as a replacement for rubber sometimes. PVC pipe can be classified by schedules e.g. Schedule 80 or Schedule 40. The schedules vary in things like pressure rating, wall thickness and color.
PVC fittings are used to join different lines together and to navigate pipes around obstacles. Popular fittings in plumbing are wyes, traps, P-traps, elbows and tees. PVC fittings have so many uses in plumbing.
To use PVC in plumbing, you must consider some things. When water passes through PVC pipes, it makes more noise than when it passes through copper pipes. The insulation of PVC is not as good as that of copper pipes. This means that you can have water freezing in pipes at low temperatures. But if you insulate PVC pipes you can solve both problems because insulation for pipes insulates both sound and temperature. This makes PVC a perfect material for plumbing.
