2 SEPTON TM and HYBRAR TM �
HYBRAR™ is a truly unique block copolymer consisting of polystyrene end blocks and a vinyl bond rich poly-diene mid- block. Due to its peak tan delta over a broad temperature range, HYBRAR™ exhibits high vibration damping and shock absorption properties. Unlike PVC and other SBCs, products manufactured using HYBRAR™ do not need a plasticizer. The highly elastic styrenic block copolymer HYBRAR™ can be processed in a wide variety of forms, including films, tubes, foams, and injection molding. HYBRAR™ products are available as hydrogenated and non- hydrogenated grades. Hydrogenated grades of HYBRAR™ have excellent compatibility with polypropylene resulting in excellent transparency and clarity when blended.
