Innovative Ultra-Thin Frame Material “TROGAMID®” Adopted in Seiko Optical Products’ New Eyewear Series

Polyplastics-Evonik Corporation

Combining Lightness and Luxury: The “Seiko Light and Fitting – Black Leaf” Series

Polyplastics-Evonik Corporation (Head Office: Shinjuku-ku, Tokyo; President: Vitor Lavini) is pleased to announce that its high-performance transparent polyamide “TROGAMID®” has been adopted in the new “Seiko Light and Fitting – Black Leaf” eyewear series by Seiko Optical Products Co., Ltd. (Head Office: Chuo-ku, Tokyo; President: Atsushi Iwasaki).

This innovative eyewear frame was developed to meet the seemingly contradictory demands of a luxurious yet comfortable design. Seiko Optical Products sought new material possibilities from the early stages of development to achieve a “thin, lightweight, and luxurious design” that was difficult to realize with conventional acetate materials. Their attention turned to TROGAMID®.

A developer from the Frame Division at Seiko Optical Products commented:
“When frames are heavy, they put pressure on the ears and nose during long wear. On the other hand, if they’re too light, they can lose their sense of luxury. TROGAMID® enabled us to achieve both.”

TROGAMID® was highly evaluated as an ideal material for eyewear frames. Its high toughness allows for thin, lightweight, and durable designs, providing a comfortable wearing experience. The frames also feature a luxurious design with the “TROGAMID®” logo engraved in gold, directly conveying the material’s reliability and brand value to users.

Polyplastics-Evonik Corporation will continue to support product development across various industries, including eyewear, through the provision of high-performance resins.
