Styrene-Ethylene-Butylene-Styrene (SEBS)
Styrene-Ethylene-Butylene-Styrene (SEBS)
SEBS technology involves the use of a catalytic system based on titanium complex and an alkyl metal prepared directly inside the hydrogenation reactor (in situ technology) for the complete hydrogenation of the diene part of a SBS having a predefined macro and microstructure.
If the hydrogenation reaction is inserted in a pre-existing SBS line, a customization of the technology may be necessary to take into account the chemistry of the existing process (interactions between process chemicals of the parent polymer and the hydrogenation catalyst).
Process steps & Features
- In-situ catalyst preparation
- Hydrogenation
- Other units of SBS process
- High hydrogenation process control
- High hydrogenation degree
- Possible product tailoring depending on customer requirements
- Possible multiarm SEBS development for Viscosity Index Improvers (VII)
- Possible functionalized degrees preparation off line using a co-rotating screw extruder
