            ViviOn? (CBC) - Cyclic Block Copolymers (CBCs)

            New Product - ViviOn? (CBC)
            ViviOn? is a family of novel cyclic block copolymers (CBCs), which are fully hydrogenated polymers based on styrene and conjugated dienes via anionic polymerization. This advanced material has remarkable thermal stability, excellent UV durability, extra-high transparency, low water absorption, low density and superb purity. These features offer the users of ViviOn? with superior design flexibility, easy processing capability and low life-cycle costs. In addition, the flexibility of tailoring polymer micro-structure by adjusting the ratio of poly(cyclohexylethylene) (PCHE) and ethylene-co-1-butene (EB) provides ViviOn? a wide range of properties from rigid plastics to soft elastomers.
