Styroflex 2G66

The product line Styroflex® comprises thermoplastic elastomers from clear styrene butadiene copolymers (S-TPE), which are more polar than comparable SBS or SEBS grades. The grades provide a very high puncture resistance to foils in multilayer applications and increase as additive the toughness of compounds. They are easy to process and work as modifiers and compatibilizers in many polymers, e.g. polyolefins. For all Styroflex® grades food contact statements are available upon request. Styroflex® 2G66 is suitable for extrusion (blown and cast film) and injection molding and offers a combination of high resilience and toughness with good transparency and process stability. 2G66 is also offered for medical applications and is Gamma, X-ray & ETO sterilizable.
