 ＜Overview of the Award-Winning Invention＞

Name: Lightweight and Highly Processable Polarized Lenses for Sunglasses (Product Name: TROGAMID^® CX Polarized Sheet)

Patent Name: "Functional Optical Lens and Its Manufacturing Method," Patent Number: 4987297

Inventors: Toshihiko Fujinaka, Masakazu Tokunaga

Details:

 This technology, primarily  designed for sunglasses, eliminates the limitations of combining lens and frame materials, enabling unprecedented lightweight and design possibilities. By using polyamide, which has excellent chemical resistance and impact resistance, as the material for the polarized sheet and lenses, it allows for combinations with various frame materials and direct fine processing on the lenses, which was difficult with conventional plastic lenses. This enables the production of sunglasses with rich design features.

  Based on this patent, Polyplastics-Evonik is developing a business around CX films and CX polarized sheets for polarized sunglasses lenses using TROGAMID^® myCX, a transparent nylon.

TROGAMID^® is a registered trademark of Evonik Industries, and Polyplastics-Evonik Corporation is the distributor in Japan.
