Barium Sulfate Healthcare Silicone Color Masterbatch ‑ White

  • A white, single component masterbatch, with the consistency of a low viscosity paste
  • Consists of Barium Sulfate dispersed in a vinyl-functional silicone polymer which covalently bonds into the matrix of platinum-cured silicone systems
  • For easy and more precise addition of Barium Sulfate toliquid silicone rubbers and low consistency elastomers suitable for injection molding
  • Reduces production time and eliminates use of powders that may contaminate clean room environments
