Dow Corning® QP1 Liquid Silicone Rubbers (LSRs)

Dow Corning® QP1 LSR materials are a series of two-part platinum, catalyzed silicone elastomers specifically designed for medical devices and device components including those intended for human implantation for less than 30 days and non-implant applications. LSRs are pumpable thermoset silicone elastomers ideal for liquid injection molding to design intricate and close-tolerance parts. Each QP1 series elastomer is supplied in a two part kit (Part A and Part B) and the series offers a range of Shore A hardness from 20 to 75.

    Uses:

  • Injection molding of precision and intricate parts of medical devices (e.g. O-rings, catheters, access valves, diaphragms, stoppers and closures)
  • Mesh or fabric coating
  • Short-term implants such as wound drains and gastric feeding tubes that are in place for 29 days or fewer
  • Non-implant, needleless access valves
  • Anesthesia masks
  • Surgical instruments
  • Dental applications
  • Nasal aspirators

    Advantages:

  • Tissue Culture testing warranted
  • Less downtime to achieve greater cost efficiencies
  • Formulated to reduce mold fouling, resulting in longer run times before cleaning
  • Heat-cured, can be post-cured but not required to stabilize physical properties
  • 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
  • Wide Shore A hardness range across grades (20-75)
  • FDA food grade compliant formulation, meets selected biocompatibility standards and in accordance with ISO 9001 standards and certified U.S. Pharmacopeia Class VI
  • Additional attributes for QP1 2XX Series:Wider process window, Shortened process cycle time, Formulated to significantly reduce mold fouling, Enhanced throughput to limit cleaning and change-outs over time, and Low viscosity material flows into intricate molds at lower pressures with greater molding consistency
