Class VI Line




  • A two-part, high consistency elastomer designed for optimal performance in a wide range of applications
  • Produces a tough, durable, translucent elastomer when thermally cured
  • Has a non-tacky surface and no volatile byproducts or peroxide residues
  • Advantages include: lot-to-lot consistency and cost-effectiveness
  • 1:1 Mix Ratio (Part A:B)


  • For a wide variety of fabrication techniques for the healthcare industry including: molding, calendering and extruding
  • Can be used with NuSil’s Healthcare color masterbatches for applications requiring colored silicones
Regulatory Support
NuSil Technology’s Class VI (C6) products meet the requirements defined in ISO-10993 for Surface Devices with “limited” (<24 hours) or “prolonged” (1 to 30 days) contact duration
After post-cure, material meets or exceed the extraction requirements for FDA regulation 21 CFR 177.2600 “Rubber Articles Intended for Repeated Use (Food Contact)” NuSil Technology’s SIL2-5070 shall not be considered for use in human implantation for a period of greater than 29 days.
