What is Polyvinyl chloride?
Polyvinyl chloride (PVC) is the world's third most widely produced synthetic polymer. It is made from vinyl chloride monomers (–CH₂–CHCl–)n by addition polymerisation. PVC is inherently rigid but is commonly plasticised with phthalates or other plasticisers to produce flexible PVC. It has excellent chemical resistance and flame-retardant properties due to its chlorine content, making it suitable for a wide range of construction, medical, and electrical applications.
