Poly(vinyl chloride) (PVC) is the third-most produced plastic, used primarily in construction due to its durability and cost-effectiveness compared to traditional materials. It has diverse applications, including pipes, flooring, and various building components, benefiting from its versatility and high performance, though it requires careful temperature management and additives for stability. Recent innovations in PVC applications at events like the London Olympics showcase its recyclable and innovative potential for structures and safety systems.

3. PVC-Poly(Vinyl Chloride)
Poly(vinyl chloride), commonly abbreviated PVC, is the third-most widely produced plastic,
after polyethylene and polypropylene.PVC is used in construction because it is more effective than traditional
materials such as copper, iron or wood in pipe and profile applications. It can be made softer and more flexible
by the addition of plasticizers, the most widely used being phthalates.
Only this much is not the introduction……….

4. PVC was accidentally discovered at least twice in the 19th century,
first in 1835 by French chemist Henri Victor Regnault and
then in 1872 by German chemist Eugen Baumann . On both
occasions the polymer appeared as a white solid inside flasks of vinyl
chloride that had been left exposed to sunlight. In the early 20th
century the Russian chemist Ivan Ostromislensky and Fritz
Klatte of the German chemical company Griesheim-Elektron both
attempted to use PVC in commercial products, but difficulties in
processing the rigid, sometimes brittle polymer blocked their
efforts. Waldo Semon and the B.F. Goodrich Company developed a
method in 1926 to plasticize PVC by blending it with various additives.

7. Mechanical properties
• PVC has high hardness and mechanical
properties.
• The mechanical properties enhance with the
molecular weight increasing, but decrease
with the temperature increasing.
• The elastic modulus can reach to 1500-3,000
MPa.
• The soft PVC (Flexible PVC) elastic is 1.5-15
MPa. However, elongation at break is up to
200% -450%. PVC friction is ordinary, the static
friction factor is 0.4-0.5, the dynamic friction
factor is 0.23.

8. Mechanical properties
• Creep Modulus For PVC, the modulus or stress/strain relationship must
be considered in the context of the rate or duration of loading and the
temperature.
• Plastics generally show excellent performance under abrasive conditions.
Abrasion Resistance

9. Thermal properties
• The heat stability of PVC is very poor, when the
temperature reaches 140 °C PVC starts to
decompose.
• Its melting temperature is 160 °C.
• The linear expansion coefficient of the PVC is small
and has flame retardancy, the oxidation index is up
to 45 or more.
• Therefore, the addition of a heat stabilizer during
the process is necessary in order to ensure the
product's properties.

10. Electrical properties
• PVC is a polymer with good insulation
properties but because of its higher polar
nature the electrical insulating property is
inferior to non polar polymers such
as polyethylene and polypropylene.
• As the dielectric constant, dielectric loss
tangent value and volume resistivity are high,
the corona resistance is not very good, it is
generally suitable for medium or low voltage
and low frequency insulation materials.

14. Application near ourselves…

15. Flooring
• Flexible PVC flooring is inexpensive and used in a
variety of buildings covering the home, hospitals,
offices, schools, etc.
• Complex and 3D designs are possible due to the prints
that can be created which are then protected by a clear
wear layer. A middle vinyl foam layer also gives a
comfortable and safe feel.
• The smooth, tough surface of the upper wear layer
prevents the build up of dirt which prevents microbes
from breeding in areas that need to be kept sterile,
such as hospitals and clinics.

16. Benefits of PVC flooring
• Durable
• Freedom of aesthetic effects – available in a
wide range of colours and patterns
• Ease of installation, easy to clean
• Easily recyclable
• Variable thickness

18. Pipes
PVC pipes have been in use for over 60 years. When compared
with traditional pipe materials, PVC offers valuable energy
savings during production, low cost distribution and a safe,
maintenance-free lifetime of service.
PVC pipes will not degrade to damage the environment and
suffer fewer breaks / leaks than other alternatives.
PVC is widely specified for pipeline systems for water, waste and
drainage due to its a theoretical service life of hundreds of years
for buried pipes. PVC pipes suffer no build-up, pitting, scaling or
corrosion and provide smooth surfaces reducing energy
requirements for pumping.

20. Covering
• PVC sheets are also used as coverings like the
sheds in railway platforms ,air base shed ,
nurseries made of PVC.
• This is very cost effective as compared to
traditional tin shed which are very heavy and
have heat absorbent nature .

23. Use of PVC in LONDON OLYMPICS
Recent mass uses of PVC

24. Applications of PVC in London
Olympics
• Tensile fabric structures
• Cables
• Pipes
• High performance sports surfaces and seating
• A very large amount of the PVC used, especially in temporary structures, has
been recycled thanks to technologies like Texyloop, which has been developed
with the support of Vinyl 2010. Some structures have been completely
dismantled and shipped to Brazil where they will be re-used in the football
arenas being built for the next FIFA World Cup in 2014.

25. • Lighter in weight as compared to traditional
materials like copper , wood and tin etc.
• Easily available and producible.
• Heat resistant and do not conduct electricity.
• Can be casted to any shape.
• Can be recycled and reused.
• Can be easily shifted from one place to
another.
Advantages of PVC

26. • It is not recommended for use above 343K
although it can be taken to 353K for short
periods
• Sensitive to UV and oxidative degradation.
• HCl is evolved when it is decomposed.
• Its production causes pollution.
Disadvantages of PVC

27. Environmental Effect
• The study 'A discussion of some of the
scientific issues concerning the use of PVC' (1)
by the Commonwealth Scientific and
Industrial Research Organisation (CSIRO) in
Australia concluded in 2000 that PVC in its building
and construction applications has no more effect on the
environment that its alternatives.

29. Conclusion
•
PVC is replacing traditional building materials such as
wood, metal, glass, concrete and clay in many
applications.
Versatility, cost effectiveness and an excellent record of
use mean it is the most important polymer for the
construction sector
It is used in drinking water and waste water pipes,
window frames, flooring and roofing foils, wall coverings,
cables and many other applications. These products are
often lighter , less expensive and offer many performance
advantages..
