Polycarbonate PC
Polycarbonates (PCs) are highly transparent engineering thermoplastics. They are exceedingly firm, stiff, hard and impact resistant, plus they are very suitable for electrical insulators.
Polycarbonates are resistant against water, many mineral acids as well as watery solutions of neutral salts and oxidizing agents. They can be processed with any methods commonly applied to thermoplastics.
Their low scratch resistance can be compensated with coatings based on e. g. polysiloxane, polyepoxy or polyurethane acrylate. Even a polysiloxane varnish only 5-8 micrometers thick is sufficient to provide the semi-finished polycarbonate product or workpiece with a surface as hard as glass, without diminishing its hot forming properties.
The material’s chemical and UV resistance can be significantly enhanced through suitable varnishes. Moreover, specialized coatings provide polycarbonates with self-cleaning or waterproof surfaces. As a compound with transparent thermoplastic polyutheranes (TPUs), polycarbonate can easily be made into lightweight, UV-resistant laminated safety glass panes.
Among other things, polycarbonates are used for:
-
CDs, DVDs and blu-ray discs
-
Spectacle lenses and optical lenses
-
Headlight diffusers
-
Aircraft windows
-
Anti-theft glazing
-
Underwater housing for cameras
-
Back covers over mobile phones (mostly smart phones) and tablets
-
Conservatory and greenhouse glazing
-
Solar panels
-
Helmets and visors
-
Camping crockery
