Cyclo Olefin Polymer (COP), which was developed by Zeon Corporation, is well known and used as an optical plastic
in optical markets, having unique properties such as high light transmission, low water absorption, low birefringence
etc. Optes Inc, who is ZEON CORPORATION's affiliate optical parts manufacturer, has succeeded in the development
of high performance optical base films. These are used for retardation and polarizing films in LCD's (Liquid Crystal
Displays), made from Cyclo Olefin Polymer with own film extrusion technologies. The Optical base film developed by
Optes Inc has superior properties compared with those of existing products such as polycarbonate (PC), polyethylene
terephthalate (PET) and Triacetate Cellulose (TAC) base in terms of low birefringence, high optical isotropy and high
dimensional stability under high humidity and temperature conditions.
