Microcellular Foaming of Cyclic Olefin Copolymer (COC)

Introduction Cyclic olefin copolymer (COC) is a commercially available thermoplastic. It possesses exceptional clarity in its natural form, similar to that of glass, and it has high moisture resistance and low absorption rates. This thermoplastic’s many qualities make it an exceptional candidate for many applications, ranging from optics to packaging. The ability to create microcellular plastic foams using COC would further increase its range of applications with a significant reduction in material usage. Technology Description Professor Kumar at the University of Washington has developed a process for creating microcellular foams from cyclic olefin copolymer (COC). Using this technique, they have been able to synthesize and characterize both thin films and thick sheets of microcellular COC foam with a broad range of relative densities (as low as 8%). This process is environmentally friendly. Business Opportunity With its high clarity and moisture resistance, this thermoplastic has a wide range of applications including packaging in the electronics, food, and pharmaceuticals industries. Its exceptional clarity makes it ideal for optics such as with lenses and monitors. Its high purity also makes it available for biomedical applications. Stage of Development Professor Kumar has characterized this process. Intellectual Property Position The UW has filed a patent on this technology. For more information on this technology contact:
