Kraton G1650 E is a clear linear triblock copolymer based on styrene and ethylene/butylene, S-E/B-S, with bound styrene of 29.2% mass. It is supplied from Europe in the physical forms identified below.

  • Kraton G1650 EU - supplied as an undusted fluffy crumb
  • Kraton G1650 ES - supplied as fluffy crumb dusted with amorphous silica

Kraton G1650 E is used for formulating adhesives and coatings, as base material for compound formulations, as a modifier of thermoplastics and as a modifier of bitumen. The inherent stability of the mid block suggests the use of G1650 E in applications that must withstand weathering and high processing temperatures.
