PVC(Poly Vinyl Chloride) was synthesized
first in 1835 by a French chemist
V. Regnault and was made commercially
available in the United States
(1933), Germany (1935), and Japan
(1941), thanks to UCC succeeding
in the development of the Mass
Polymerization method. Initially,
PVC was mainly used for making
wire insulation, raincoats, and
soles.
During the 1960's, U.S. chemical
companies such as Dow, Goodrich,
and others in Japan produced VCM
(Vinyl Chloride Monomer) by Oxy
Chlorination method, boosting
PVC manufacturing. VCM monomer
is composed of carbon, hydrogen
and chlorine and turns into PVC
when it is polymerized. PVC is
one of the most commonly manufactured
Plastics that we use in every
day life since it is permanent
and easy to process by various
methods. As synthetic leather,
pipe, wrapping material, and wall
paper, PVC is highly essential
to our life.
PVC is manufactured in three different
methods: Suspension, Emulsion,
and Mass Polymerization. Approximately
80% of PVC, worldwide, is produced
by Suspension, 10% by Emulsion,
and the remaining 10% by Mass
Polymerization.
