Cyclic Olefin Copolymers target optical components.

Press Release Summary:



Suited for printer f-theta lenses, telephone camera lenses, and light guide plates, Topas® TKX-0001 COC has heat deflection temperature of 127°C and glass transition temperature of 140°C. In addition to optics, it can be used in thin-walled injection molding applications. With heat deflection temperature of 95°C and glass transition temperature of 110°C, Topas 5010L-01 COC is suited for large light guide plates and large diffusion plates.

Ticona Introduces Two Improved Optical Grades of Topas® COC



Florence, Ky.; Kelsterbach, Germany, May 13, 2005 - Ticona, the engineering polymers business of the Celanese Corporation, has introduced two improved grades of Topas® cyclic olefin copolymer (COC) for injection molded lenses and other optical components. The new grades, Topas TKX-0001 and 5010L-01 COC, have excellent clarity and transparency, flow well in molding, and replicate small features precisely. They also are low in color and birefringence and, because they absorb just 0.01 percent water, are dimensionally stable as humidity changes.

Topas TKX-0001 COC is designed for such uses as printer f-theta lenses, telephone camera lenses and light guide plates. It has a heat deflection temperature of 127°C, a glass transition temperature of 140°C and releases well from the mold. In addition to optics, it can be used in many thin-walled injection molding applications that need high flow and good release properties.

Topas 5010L-01 COC has a heat deflection temperature of 95°C and a glass transition temperature of 110°C. It offers excellent processing freedom and can be injection molded at a much lower temperature than Topas TKX-0001 COC. It also has higher melt flow, so it fills larger and more complex components. It is intended for use in large light guide plates and large diffusion plates, such as those found in LCD televisions, notebook computers and other displays.

The properties that make these two grades suitable for optical applications, also position them for a variety of medical, diagnostic and drug discovery devices. In particular, they can be used for microtiter plates having a high well density and microfluidic devices that call for molding small features precisely.
