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
