Styrene Ethylene Butylene Styrene is the hydrogenated version of the polymer Styrene Butadiene Styrene. Hydrogenation is the process of reaction a substance with Hydrogen. The effect of this hydrogenation is that SEBS has far superior weathering resistance and thermal stability than SBS, whilst retaining most of the elastic properties of SBS. In general, SEBS ages far better than SBS.
SEBS belongs to the much larger family of plastics, the Thermoplastic Elastomers. Both SEBS and SBS are styrene copolymers, meaning that they are a mix of two different types of monomers. Copolymers allow manufacturers to combine the desirable properties of multiple polymers. SEBS and SBS polymers consist of a long chain of polybutadiene sandwiched between two chains of polystyrene however in SEBS the polybutadiene chain has been converted to ethylene-butylene through hydrogenation. SEBS is usually printed at a temperature between 230°C and 250°C.
SEBS is similar to rubber in its properties. It is strong, soft and flexible. It is particularly well suited to printing things that need to dampen vibrations or any product that needs to retain its soft and flexible properties under weather or heat exposure.
