Implant Line




  • High tensile strength, low modulus high consistency silicone rubber
  • Low tensile set and low hysteresis qualities
  • Cures with heat via addition-cure chemistry
  • 1:1 Mix Ratio (Part A: Part B)


  • For a wide variety of fabrication techniques for the medical device industry including: molding, calendering and extruding
  • Useful in applications where low modulus and high strength are needed
NuSil Technology MED-4727 may be considered for use in human implantation for a period of greater than 29 days.
