APEL™, cyclic olefin Copolymer of Mitsui Chemicals product, is TM amorphous and transparent resin with excellent optical properties. Characteristics of APEL™ has been contributing to “smaller and lighter lens design”, with its highest refractive index and lowest birefringence among amorphous polyolefins, and enables replacement of conventional Low lens materials such as glass or PMMA. Dimensional Electrical APEL™ maintains its performance in the severe environment such as Stability Birefringence Characteris- high humidity, high temperature, hence it is suitably adopted for new High tics applications such as lenses for Automotive Camera and Head Refractive Mounted Display (HMD). Index In addition, APEL™’s excellence in moisture barrier, electric proper- ties, and chemical resistance has been perfectly fit for food and medical packaging. High Heat Resistance APEL™ stays innovative and is fitting to various advanced market High Moisture High needs. Resistance Transparency “Have Freedom in Optical Design, Have Clearer View of the Future” is the key message of APEL™ to the industry and society. Easy Moldability Cyclic Olefin Copolymer x Ethylene APEL™ is Cyclic Olefin Copolymer (COC) Unit produced by copolymerization of ethylene and cyclic olefins.
