APEL™, cyclic olefin Copolymer of Mitsui Chemicals product, is amorphous and transparent resin with excellent optical properties. 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 lens materials such as glass or PMMA.

ADVANTAGES

1. Improves image quality.

2. Controls lens curvanture, Enhances design freedom.

3.Contributions to thinner lens units.

4. Excellent dimensional stability with little mositure adsorption.

5. Little effect on drugs due to low elution.

6. Has low moisture permeability coefficient.

7. Provides good barrier performance.
