Polyvinylchloride(PVC) is a very important plastic material in the chemical industry.
Polyvinyl chloride is prepared by polymerization of the monomer vinyl chloride.
The annual global production of vinyl chloride is about 17 million tons in 1985.
more than 64% of VC is produced in Europe and the USA. About 95% of the world’s production of vinyl chloride is used to produce polyvinyl chloride.
The scientist Regnault discovered Polyvinylchloride accidentally in the 19th century first in 1835. The Regnault polymer appeared as a solid white material inside the vinyl chloride vials that were left exposed to sunlight.
This polymer is unstable in the direction of light and heat and this leads to widespread changes in structure due to the removal of HCl and this also affects its physical, chemical and mechanical properties. ,
Uses of PVC:
Globally more than 50% is the plant’s PVC is used in the Construction industry due to low production cost, endurance, and lightweight.
It works as a mineral substitute for many applications where rust can negatively affect metal functions and increase its maintenance costs.
PVCM engaged in any of the world’s pipes. PVC doesn’t need welding . as it can be connected using joints, cement, solvents, and special adhesives.
You can also find PVC is the electrical components industry such as electrical insulation, wiring, and cable coatings.
In the healthcare industry, PVC has popular uses in make feeding tubes, blood bags, intravenous bags and as parts of dialysis machines and many other elements, and
there are concerns about the impact of PVC on the environment and human health:
PVC has certain toxicity which is caused by toxins that can be released during manufacturing and when exposed to fire it decomposes in landfills.
These toxins have been linked to health problems such as cancer, birth growth problems, endocrine disorders, asthma and lung problems.
While many PVC manufacturers consider the high salt content as an advantage, salt is considered the key ingredient in releasing toxic dioxin and phthalates.
The average PVC price is the US $ 680-800 / Ton with an expected continuous increase in PVC price by 2020 due to increasing global demand for PVC.
