Kraton G1654 H is a linear triblock copolymer based on styrene and ethylene/butylene. It is supplied from North America in the physical
form identified below.
Kraton G1654 HU - supplied as an undusted powder
Kraton G1654 HS - supplied as a dusted powder
Kraton G1654 H 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 H in
applications that must withstand weathering and high processing temperatures.
