PVC was first developed in 1925
A polyvinyl chloride (PVC) pipe is made from a plastic and vinylcombination material.
The pipes are durable, hard to damage, and long lasting.
A PVC pipe does not rust, rot, or wear over time. For that reason, PVC piping is most commonly used in water systems, underground wiring, and sewer lines.

PVC INTRODUCTION
Polyvinylchloride (PVC) [-(-CH2 -CHCl-)n-]
is one of the three most important polymers currently used worldwide.
the cheapest polymers
a large range of properties
hundreds of products.
PVC is formed by the polymerisation of vinyl chloride (chloroethane) monomer units:
