ZEON Corporation held a groundbreaking ceremony today at its Mizushima Plant (Kurashiki, Okayama Prefecture) to commemorate the construction of a new facility which will produce COP (Cyclo-Olefin Polymer; product names ZEONEX® and ZEONOR®), a high functional, thermoplastic transparent resin.
The facility will mainly produce ZEONOR®, a high functional resin used in the optical film, ZEONOR Film®.
The annual capacity of the existing facility was expanded to 10,000 tons in June 2005 and further expanded to 13,000 tons in May 2007. The new facility under construction will have the same capacity as the existing facility. With the completion of the new facility, total production capacity for COP combined with ZEONEX® will increase to 31,000 tons per year. Construction is scheduled to be completed at the end of July 2008.
ZEONOR® is used not only as a material for optical films but in a variety of other areas including light-guide plates and diffusion plates for LCDs, and demand has been rising dramatically in the recent years.
ZEONOR® has the following property of:
(1) Extremely low moisture permeability and excellent dimensional stability
(2) High transparency across a wide wavelength range
(3) Low optical anisotropy; low dispersion and low light elasticity, which are superior properties required for optical film materials
