SSBR
Solution Polymerized Styrene Butadiene Rubber
KUMHO Solution SBR is a synthetic rubber product manufactured by solution-polymerizing organic solvents, such as styrene and butadiene with alkyl lithium. Compared to the existing SBR manufactured by emulsion polymerization, it has far better viscoelasticity so it is used to produce safer and more fuel-efficient tires. We used silica-compatible compound, called siloxane as the coupling agent for the first time in the world so it offers advantageous physical properties for silica tires.

Usage

  • High-performance tires
  • Shoes
  • Belts
  • Rubber hoses

Features

  • Great processability and mechanical properties
  • Excellent filler dispersibility
  • (Compared to ESBR) better fuel efficiency and braking performance (-> mainly for eco-friendly and high-performance tires)
