Styroflex^®

Styroflex^® is a styrene-butadiene block copolymer (SBC) with the properties of a thermoplastic elastomer (S-TPE), suitable for extrusion (including both blown and cast film) and injection molding. Characterized by a combination of high resilience and toughness, optical clarity and process stability Styroflex^® offers as well a good printability and good adhesion to many different polymers. In film applications, Styroflex^® provides excellent stretch recovery, superior transparency and puncture resistance, high oxygen and moisture permeability. It is also employed as a high performance additive to increase toughness and e.g. the stress cracking resistance of styrenic and olefinic polymers.
