Specialty Liquid Silicone Rubbers

High Clarity Liquid Silicone Rubber

DESCRIPTION
  • Two-part, high clarity silicone system designed for use in injection molding equipment
  • Cures with heat via addition-cure chemistry
  • 1:1 Mix Ratio (Part A: Part B)
APPLICATION
  • For the injection molding of parts requiring a high clarity / high durometer material including: molded rubber stoppers, gaskets, seals, valves, o-rings and other precision parts
  • Suitable for over-molding applications (may require use of a silicone primer for improved adhesion)
  • Can be used with NuSil's Healthcare color masterbatches for applications requiring colored silicones
