Liquid Silicone Rubbers

Liquid Silicone Rubber

  • Two-part, white silicone system designed for use with injection molding equipment
  • Cures with heat via addition-cure chemistry
  • 1:1 Mix Ratio (Part A: Part B)
  • High tear strength
  • Designed to resist blocking and rehealing that otherwise might be induced by the radiation sterilization of molded parts.
  • For the injection molding of parts requiring a material with a medium durometer including: molded rubber stoppers, gaskets, seals, valves, o-rings and other precision parts
  • Suitable for over-molding applications
  • Can be used with NuSil's Healthcare color masterbatches for applications requiring colored silicones
