APEL is a cyclo olefin copolymer (COC) that integrates the performance of polyolefin resins and that of amorphous resins. With the highest refractive index among the amorphous polyolefins, APEL cyclo olefin copolymer is low in optical anisotropy and essentially low in birefringence. This makes it ideal for optical plastic lenses. With excellent moisture-proof properties, resistance to chemicals and non-attachment characteristics, APEL cyclo olefin copolymer is also used for medical packaging material. Its many functions and superior characteristics create new potential for transparent materials.
With its high refractive index and low birefringence, APEL cyclo olefin copolymer is ideal for high-transparency optical plastic lenses.
With the lowest moisture permeability coefficient among transparent resins, APEL cyclo olefin copolymer is perfect for moisture-proof containers and films.
Resistance to chemicals
APEL cyclo olefin copolymer is so chemically stable that it exhibits a high level of resistance to acids, alkalis and polar solvents.
APEL cyclo olefin copolymer has superior electrical characteristics that are inherent to polyolefins. It also excels in high frequency characteristics.
Amorphous qualities provide APEL cyclo olefin copolymer with high levels of dimensional accuracy and freedom from dimensional variations due to water absorption.
Outstanding resistance to heat
As part of its mechanical properties, APEL cyclo olefin copolymer is low in temperature dependency. It is possible to freely control its heat resistance by changing the copolymerization ratio between ethylene and cyclo olefin.
APEL cyclo olefin copolymer's fluidity can be freely controlled by adjusting its molecular weight. This enables enhanced fluidity.
