TROGAMID® UV eCO is an additive master batch based on a transparent polyamide containing an UV absorber. The master batch can be mixed with granules of TROGAMID® CX7323, myCX high flow, CX9701 or CX9710 to achieve a high UV absorption for wave lengths shorter than 400nm (UV cut-off 400). This property is mandatory for the production of high-quality sunglass lenses. Transmission, tested according to ISO 13468-2 on 2 mm thick specimens: (adding 5% TROGAMID® UV eCO in TROGAMID® CX7323, TROGAMID® myCX high flow or TROGAMID® myCX eCO) Wave length 400 nm approx. 9 % Wave length 380 nm approx. 3 % Transmission, tested according to ISO 13468-2 on 2 mm thick specimens: (adding 10% TROGAMID® UV eCO in TROGAMID® CX7323, TROGAMID® myCX high flow or TROGAMID® myCX eCO) Wave length 400 nm approx. 5,0 % Wave length 380 nm approx. 2,5 % TROGAMID® UV eCO is supplied as cylindrical pellets in moisture-proof polyethylene packaging Industrial Sector: Sustainable, Optics, Sports and Lifestyle Sustainability: eCO Delivery form: Pellets, Granules Optics: Transparent Resistance to: UV / light / weathering Additives: Unfilled Applications: (Sun-) glasses, Lenses Additives: Light stabilizer Delivery form: Cylindrical pellets Dry properties listed below Information provided by Evonik. |
