Covestro Makrolon ET3117 550115 PC Advantage

• UV-resistant polycarbonate. Compared to the more commonly used Makrolon ET 3113 PC resin in the same series, the main difference with Makrolon ET 3117 is the addition of UV stabilizers, which make it suitable for manufacturing products intended for outdoor use as well as housings for small household appliances that are exposed to prolonged UV radiation, effectively extending the products’ service life.
• Good processability. As a PC resin specifically designed for the production of profiles,the melt index of Makrolon ET 3117 PC is 6.5g/10min at 300℃ and 1.2kg test environment, Higher polymer viscosity and lower flow rates help prevent edge defects and warping in the profile production process, significantly improving the yield rate.
