Polycarbonate (PC).
Polycarbonate is transparent, extremely durable, and resistant to heat. Because it is more costly, PC is used only in applications where other plastics are too soft, fragile, easily scratched, dimensionally unstable or too unclear.It is used in a broad range of items: CDs and DVDs, electronic and device components, eyeglass lenses, optical lenses, light covers, headlight diffusers, windshields, aircraft windows, safety glass in e.g. police cars, anti-theft glass for industrial doors, underwater housing for cameras, conservatories and greenhouses, solar panels, porch roofs, packages and bottles, suitcase shells, carriages for constructing functional models, helmets and visors, single-use medical products, and more.
Buhler sold the first system for conditioning PC flakes in the early 1990s to Dow. Other lines followed for customers in the USA, Germany, Japan and Korea.
