Kraton G1654 E is used as a base material for themoplastic elastomer (TPE) compound formulations for a variety of applications. It is also used as a modifier of thermoplastics and bitumen. The inherent stability of SEBS polymers suggests the use of G1654 E in applications that must withstand weathering and high processing temperatures.
