APEL is a cyclo olefin copolymer (COC) developed by Mitsui Chemicals using Ziegler polymerization technology. Integration of the performance of polyolefin resins and that of amorphous resins enables control of heat resistance and fluidity. With the highest refractive index among amorphous polyolefins, it is low in optical anisotropy and extremely low in birefringence. Proven applications in optical plastic lenses. Excellent moisture-proof properties, chemical resistance and non-attachment characteristics that make it applicable as a medical packaging material. APEL's versatile functions and superior characteristics create new potential for transparent materials.
