Styrolux 3G46

The product line Styrolux® comprises clear styrene butadiene copolymers. The grades have in general an intrinsic toughness, are easy to process and work as modifiers and compatibilizers not only in polystyrene but in many other polymers, e.g. polyolefins. For all Styrolux® grades food contact statements are available upon request. Styrolux® 3G46 is specifically designed for sheet- and film extrusion and thermoformed articles. It shows a high performance in blends with general-purpose polystyrene, providing parts with an excellent balance of transparency and toughness. 3G46 is also offered for medical applications and is Gamma, X-ray & ETO sterilizable.
