4. The purpose of this
presentation
PC is a good material choice in
industry not only due to its
characteristics, but also
because its processing is
environmentally friendly,
and it can be recycled

5. History
1-PC was developed in 1953
by the German scientist
"Hermann Schnell" who was
chemist in German company
"Bayer"
2-PC was introduced in United
States Of America in 1960 by
the general electric company
3- finally in China

6. Definitio
n
PC known by the trademarked
names
Lexan, Makrolon, Makroclear and
others, are a particular group of
thermoplastic polymers. They are
easily worked, molded, and
thermoformed. Because of these

Reaction
1-Polycarbonate begins
with the monomer
bisphenol "A".

11. THE FINAL REACTION

12. process
Extrusion Molding
The molten PC is The PC melt is pressed
passed through a die into a mold with the
that gives the material its defined shape of the
final shape. final product.
Long pipes and sheets This process is ideal for
are created by this specific parts such as
process automotive and
computer parts

13. Flow Sheet Of the process

14. Classification of polycarbonate
Reaction to stress and temperature
Thermoplastic (can be recycled)

15. Molecular Arrangement
all the chains become tied together to form
a crosslinked material that looks like this:
