Cyclic Olefins (COP)

Thermoplastic cyclo olefin appears as an exceptionally transparent, glass-clear material with outstanding optical properties including 92% light transmission and low birefringence. Key features include exceptional clarity and optical properties, very low moisture absorption, outstanding chemical resistance to polar solvents and acids, excellent barrier properties against moisture and gases, high purity with minimal extractables, and good heat resistance. Primarily used in pharmaceutical packaging, medical diagnostic devices, high-performance optical applications, and electronic components. 

Alternatives to cyclo olefin include PMMA (acrylic) and polycarbonate. Current industry trends include variants designed for recyclability and formulations with reduced environmental impact. Major sub-type of thermoplastic cyclo olefin is COP (cyclic olefin polymer). The industry is also developing specialized grades for 3D printing applications, heat-resistant variants for sterilizable medical devices, and formulations optimized for precision injection molding of optical components.
