Kraton® G1654 E (SEBS) Linear Block Copolymer
Categories:	Polymer; Thermoplastic; Elastomer, TPE
Material Notes:	Kraton G1654 E polymer is a clear, linear triblock copolymer based on styrene and ethylene/butylene, S-E/B-S, with bound styrene of 30% mass. Kraton G1654 ES - supplied as a "fluffy" crumb dusted with amorphous silica Region: Asia Pacific, Europe, Japan, North America, and South America Uses: Kraton G1654 E is used as a base material for thermoplastic 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. Applications: Adhesives, Sealant and Coatings; Compounding and Personal Hygiene; Impact Modification; Medical; Packaging and Polymod; and Personal Care
