Evonik (Essen / Germany; www.evonik.com) has added a sustainable, high-performance moulding compound to its “Trogamid” range of transparent polyamides.

Optimised for the optics industry, “Trogamid myCX eCO” (“eliminate CO2”) is a high-purity microcrystalline PA that contains 40% biobased raw material and is produced using only renewable energy. Consequently, the material’s carbon balance is half that of the petrochemical-based product, which has been confirmed by independent certification company TÜV Rheinland (Cologne / Germany; www.tuv.com). Evonik had completed the expansion of transparent PA moulding compounds under the “Trogamid CX” trademark a year ago (see Plasteurope.com of 22.04.2020).

Evonik said the environment-friendly manufacturing process has not altered the properties of “Trogamid myCX”, which include transparency above 90%, excellent mechanical characteristics and resistance to stress cracking and breakage. The material is used in premium lenses or high-quality visors for ski and snowboard goggles.
