Evonik Displays TROGAMID for Greater Flexibility in Design of Optical Applications

Yangzhou Chengsen Plastics Co.,Ltd | Updated: Sep 30, 2018

trogamidEvonik, the creative industrial group from Germany, will be displaying an innovative technology for making eyeglasses frames: IMPLEX using TROGAMID, a transparent, high-performance plastic, at this year’s MIDO in Milan, Italy. TROGAMID offers great flexibility to eyewear manufacturers in the design of eyewear in comparison to the traditional production methods. The innovative technology facilitates cutting of the finished frames from a single, curved preform, and reduces time from the machining and finishing steps after injection molding. The preform is made of multiple functional layers comprising base frame made of TROGAMID, the adhesive and coating layers, or the scratch-resistant film.

Easy handling, excellent productivity, and the ability to customize in a variety of colors, textures, and patterns enables IMPLEX to win over the customers. The innovative technology is able to implement designs even more quickly and is a major advantage to eyewear manufacturers.

Evonik uses two material solutions to meet the customer’s demands: TROGAMID CX9704, a transparent polyamide used for the base frame for varying the shape of the product and TROGAMID CX9711 providing the second structural layer with excellent processing characteristics and high resistance to chemicals.
The development of IMPLEX is the result of cooperation between Evonik and Tungfung. Evonik offers the right material and product expertise, while Tungfung serves as an expert partner in the production of exceptional eyeglasses frames.

Tungfung offers one-stop production solution from procurement and manufacture of spectacles related raw materials and components to the provision of after-sales services to its customers.

 The Resource Efficiency segment is led by Evonik Resource Efficiency GmbH and supplies high-performance materials for environmentally friendly as well as energy-efficient systems to the automotive, paints & coatings, adhesives, construction, and many other industries.
