| Styrolux® 3G55 is a clear styrene butadiene copolymer (SBC) used mainly in sheet extrusion and thermoforming applications. It is specifically designed for improved performance in blends with general-purpose polystyrene, providing parts with an excellent balance of toughness, transparency and economics. Because of the tendency of blocking, 3G55 is mainly used in inline thermoforming. 3G55 is difficult to print and decorate since it contains a microcrystalline wax. FEATURES Outstanding toughness High GPPS blend capability Good transparency APPLICATIONS Food packaging Food service items Drinking cups Extruded films In-line thermoforming&& |
