Styrolux 3G55
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® 3G55 is mainly in sheet extrusion and thermoforming applications. It shows a high performance in blends with general-purpose polystyrene, providing parts with an excellent balance of transparency and toughness. Due to its tendency of blocking, 3G55 is mainly used in inline thermoforming. 3G55 is difficult to print and decorate since it contains a microcrystalline wax.
