| Polyvinyl Chloride (PVC) |
 |
Polyvinyl chloride (PVC) is a widely used
thermoplastic resin. Globally, more than 50%
of PVC manufactured is used in construction.
As a building material, PVC is cheap,
durable, and easy to assemble. In recent
years, PVC has been replacing traditional
building materials such as wood, concrete and
clay in many areas.
Polyvinyl Chloride is a polymer made by the
catalytic polymerization of vinyl chloride.
PVC also includes copolymers that contain at
least 50% vinyl chloride. The neat
homopolymer is hard, brittle and difficult to
process, but it becomes flexible when
plasticized. Polyvinyl chloride molding
compounds can be extruded, injection molded,
compression molded, calendered, and blow
molded to form a huge variety of products,
either rigid or flexible depending on the
amount and type of plasticizers used. There
are more compounding recipes for PVC than for
any other polymer. Rigid PVC is strong,
difficult to burn, has excellent resistance
to strong acids and bases, to most other
chemicals, and to many organic solvents.
Additionally, polyvinyl chloride is one of
the least expensive plastics.
