Cycloolefin Copolymers - New Options To Meet Demanding Requirements In Films, Laminations and Extrusion Coating, 2001 European PLC Conference Proceedings
Wolfram Goerlitz--Cyclic olefin copolymers (COC) are a class of amorphous, thermoplastic materials. Their unique property combination leads to a wide range of applications in pharmaceutical & medical packaging, capacitor films, food packaging films, optical parts/lenses, diagnostics and electrophotographic printing. As a film resin COC offers significant advantages over existing products especially when high water vapor barrier, clarity and rigidity are required. The unique combination of excellent optical, thermal, rheological, mechanical, electrical and ecologically-friendly properties and its benefits to film performance are described in the following article. Due to the flexible continuous production process the glass transition temperature, molecular weight and molecular weight distribution can be tailored independently according to the requirements of the application.
