Styrolux 656C
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® 656C shows enhanced flow properties and is used almost exclusively used for injection molding of rigid, tough parts, requiring highest levels of clarity and surface gloss. 656C is also offered for medical applications and is Gamma, X-ray & ETO sterilizable.
