Thermoplastic Rubber Styrene-Butadiene-Styrene Block Copolymer (SBS)

Dynasol's styrene-butadiene-styrene (SBS) block copolymers flow easily at processing temperatures and behave like reinforced elastic rubbers under normal application conditions. Our wide range of linear and radial elastomers can be combined with a variety of molecular weights, creating an extensive selection of polymers.

This line of SBS polymers can be used in a variety of demanding applications such as:

  • Polymer modification
  • Asphalt/Bitumen modification
  • Vulcanized Compounding
  • Adhesives
  • Sealants
