Evonik’s TROGAMID® T5000: making eyewear lighter, stronger and more efficient

November 6, 2017

TROGAMID® T5000, a semi-crystalline polyamide with a transparency of 90%, is an ideal material for optical manufacturers. Compared to other transparent polyamides, TROGAMID® T5000offers higher modulus and rigidity. Moreover, the material is especially suitable for manufacturing thin frames and semi-rimless eye wear frames, which can significantly reduce the frame weight without affecting performance. This in turn greatly improves wearing comfort.

Lighter, stronger and more efficient

Lightweight design plays an important role in many sectors, but is particularly relevant for the optical industry. The high strength and rigidity of TROGAMID® T5000enables the production of thinner and lighter eye wear frames. Additionally, TROGAMID® T5000 is more resilient than heavier conventional frames, which translates into greater freedom for designers.

While consumers tended to focus on aesthetics in the past, they now place greater emphasis on product quality and performance. Optical manufacturers carefully consider material properties for their choices. TROGAMID® T5000 is characterized by its outstanding chemical resistance, which prevents cracking from contact with chemicals. Furthermore, the material’s easy processing and coloring properties save time and money for maximum efficiency.

Cooperation of Evonik and Hwa Mao Optical (Xiamen)

This application was developed and implemented as part of a cooperation between Evonik and Hwa Mao Optical (Xiamen).

Hwa Mao Optical (Xiamen) Co., Ltd., established in 1996, specializes in manufacturing a wide variety of eyewear products.
