Mitsui to market COC resin here.Mitsui Chemicals America, Inc., Purchase, N.Y., has introduced Apel cyclic olefin copolymer Cyclic Olefin Copolymer (COC) is an amorphous polymer made by several polymer manufacturers. COC is a relatively new class of polymers when compared to polypropylene and polyethylene. (COC See chip on chip. ) to North America. The other supplier of COC here is Ticona of Florence, Ky., which aims to divest the business. Like other COCs, Apel boasts good clarity, heat resistance, and moisture barrier. Mitsui claims that Apel has higher refractive index A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two different materials, their refractive indices determine the angle of transmission (1.54) and lower birefringence Birefringence The splitting which a wavefront experiences when a wave disturbance is propagated in an anisotropic material; also called double refraction. In anisotropic substances the velocity of a wave is a function of displacement direction. than other COCs and cyclic olefins, suiting it to uses in shrink film, optical lenses for DVD players and recorders, and pharmaceutical blister packs.
