Zeon Corporation, Japan, a world leader in specialty elastomers, polymers and specialty chemicals has more than 25 years experience in product and business development with Cyclo Olefin Polymers (COP) ZEONEX® & ZEONOR®. ZEONEX® & ZEONOR®COP are fully transparent und unpolar thermoplastic resins that can be used with many plastics processing technologies. Key properties of ZEONEX® and ZEONOR® – Low specific gravity – Extremely low water absorption and moisture permeation – High mechanical stiffness , outstanding dimensional stability and excellent impact resistance – High transparency and low optical birefringence – High transmission in UV-wavelength range – Unpolar, hydrophobic and non-reactive surface – Excellent chemical resistance to acids, bases and polar media – Very high purity – Steam sterilisation resistance with selected grades – Low auto-fluorescence – Low dielectrical constant and loss factor – Direct metallisation capability by surface sputtering processes Due to their unique combination of properties ZEONEX® and ZEONOR® Cyclo Olefin Polymers (COP) make up a continuously growing market segment in several application fields, including those listed below. Medical , Pharmaceutical and Biotech Packaging and containers of drugs, vaccines and other medical/pharmaceutical products is one of the most promising longterm application ranges for ZEONEX® and ZEONOR® COP’s. Again the balance of outstanding water barrier properties in combination with high purity, excellent chemical resistance, high transparency and low interaction with drugs, put COP as a perfect alternative to glass or other plastics solutions for vials, syringes and blister film packages. Good transparency in UV-wavelength range and very low autofluorescence of COP makes them highly desirable for cuvettes, High Throughput Screening (HTS) microplates or biochips in analytical/diagnostics applications. Microfluidic arrays benefit from the excellent mouldability and precise transcription of microscopic structures.
