DuPont™ Liveo™ BioMedical Grade Liquid Silicone Rubbers (LSRs)

Liveo™ 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 30+ days and implantables. 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 to 70.

 
 
 
Uses
  • Mesh or fabric coating
  • Injection molding of precision and intricate parts of medical devices (e.g., O-rings, stoppers and closures)
  • Q7 Biomedical Grade LSRs: Class III medical devices or long-term (90+ days) implantation
Advantages
  • Heat-cured
  • Easy processing
  • Tight tensile and tear strengths
  • Contain 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
  • Meet selected biocompatibility standards and in accordance with ISO 9001 standards
  • Additional attributes for Liveo™ Q7-7840, Liveo™ Q7-7850, and Liveo™ Q7-7870 LSRs: 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
