Silastic® BioMedical Grade Liquid Silicone Rubbers (LSRs)

Silastic® BioMedical Grade LSRs are a series of two-part platinum-catalyzed silicone elastomers specifically designed for liquid injection molding or supported extrusion. This series can be used in the fabrication of medical devices and device components including those intended for human implantation for less than 30 days and non-implant applications. Each elastomer is supplied in a two part kit (Part A and Part B) and the series offers a range of Shore A hardness from 30-60.

    Uses:

  • Mesh or fabric coating
  • Injection molding of precision and intricate parts of medical devices (e.g. O-rings, stoppers and closures)
  • Short-term implants such as wound drains and gastric feeding tubes that are in place for 29 days or fewer

    Advantages:

  • Heat-cured
  • Easy processing
  • Tight tensile and tear strengths
  • Contains no peroxides, peroxide by-products, chlorophenyls or PCBs
  • No organic plasticizers, phthalates or latex additives
  • Low viscosity allows faster flow and complete fill at low pressures
  • Fast cure and batch-to-batch consistency
  • Meets selected biocompatibility standards and in accordance with ISO 9001 standards
  • Additional attributes for Q7-7840, Q7-7850, Q7-7870: Improved molding performance, Formulated to significantly reduce mold fouling, Enhanced throughput to limit cleaning and change-outs over time, and Improved mechanical properties like tear strength and compression set
