PVC Profile Industry
Polyvinyl chloride, (usually used as abbreviated PVC.) is a plastic polymer with a wide range of uses. It is the third most produced synthetic plastic polymer in the world after polyethylene and polypropylene.
It has two forms: rigid (sometimes abbreviated as RPVC.) and flexible. The solid form of PVC is used in the building industry for pipes and installation materials, and for door and window profiles. In recent years, PVC has taken its place in many areas of wood, concrete and clay, which are traditional building materials. It is also used in bottles, inedible product packages and cards (bank and member cards). It can be made softer and more pliable by the addition of plasticizers such as phthalate. This soft form is used in pipelines in the wastewater industry, electrical cable insulation, imitation leather, inflatable products. There are also application areas where it is used instead of rubber. It has also been used in the health sector for the last 50 years. PVC can be found in the bags and transfusion sets of parenterally used fluids, blood and blood products, catheters, cannulas and drains, stoma products and many more.
Producing
Polyvinyl chloride is produced by the polymerization of monomer vinyl chloride. PVC is a tough plastic, and plasticizers are added to make it softer and more flexible.
history
Polyvinyl chloride was discovered accidentally in the 19th century in two different forms, by Henri Victor Regnault in 1835 and by Eugen Baumann in 1872. At the beginning of the 20th century, Russian chemists Ivan Ostromislensky and Fritz Klatte with the German chemical company Griesheim-Elektron tried PVC in commercial products, but difficulties in processing in the solid state and the brittleness of the polymer stalled the efforts.
In 1926, B.F. Waldo Semon from Goodrich company developed a plasticization method by mixing PVC with different additives. This result yielded a more flexible and easier to process material, and widespread commercial use was achieved soon after.
PVC raw material recycling (recycling) code has been determined as 3.
PVC can be recycled about seven times and has a lifespan of about 140 years. The international recycling code is indicated as "3".
