Polycarbonate sheets:
Polycarbonate
is a polymer that is produced as a resin and marketed by GE Plastics under
the trade name 'Lexan'. Lexon polycarbonate is available in sheet form.
The material is very strong and has tremendous impact resistance and also
acts as fire retardent.
Signages
need polycarbonate sheets that are white in colour and transluscent so
that this could be used for backlighting. It is suggested to use sheets
of thickness 3mm for this purpose. It is essential that these sheets are
UV stabilised - especially if they are used outdoors.
Cold Forming: The sheets can be cold formed and bent using the normal
sheet bending equipment. Experience in this is essential, otherwise the
sheets will get bent in odd directions.
Hot Forming:
The sheets can also be Vacuum formed into
different forms using a mould. Experience in this is essential, and it
is not as easy as vacuum forming acrylic sheets.
