1. The document summarizes information about polycarbonate presented by the Smile Group to the Chemical Department faculty of engineering.
2. Polycarbonate is a thermoplastic polymer with strong, durable, and impact-resistant properties making it suitable for a variety of industrial and commercial applications.
3. The presentation covers the history, chemical structure, production process through condensation reaction, properties, classification, morphology, methods of production, mechanical strength and various applications of polycarbonate.
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

18. MECHANICAL STRENGTH AND BEHAVIOR
Polycarbonates is elastomeric
elastomer is an amorphous polymer with a special
molecular structure looking like mixed up spaghetti’s
having in addition many cross links
