Plycarbonate Sheets :
       Material and Process Specifications:


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.
