Styroflex 4G80

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® 4G80 is a styrene butadiene block copolymer (SBC) optimized for the extrusion of soft tubings. 4G80 is also offered for medical applications and is Gamma, X-ray & ETO sterilizable.
