Polycarbonates (PC):
are a group of thermoplastic polymers containing carbonate groups in their chemical structures. PC used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications.

Polyvinyl chloride (PVC):
Is the world’s third-most widely produced synthetic plastic polymer, after PE and PP; about 40 million tones are produced per year.
PVC comes in two basic forms, rigid and flexible. The rigid form is used in construction for pipe and in profile applications such as doors and windows. It is also used in making bottles, non-food packaging, and cards. It can be made softer and more flexible by the addition of plasticizers. In this form, it is also used in plumbing, electrical cable insulation, imitation leather, flooring, signage and many applications where it replaces rubber.
