Liquid Silicone Rubber (LSR) Materials

Benefits
  • Bio-inert, suitable for medical and food-grade applications.
  • Can be sterilized using ETO, Autoclave, E-beam and Gamma radiation processes.
  • Excellent stability over a wide range of temperatures (-150°F to 450°F).
  • Low viscosity, can fill into thin wall geometry as low as 0.004”.
  • Low compression set, well suited for sealing applications.
  • Excellent electrical insulating qualities even under severe environmental stress
  • Easy to blend any color based on PMS color standards.
Applications
  • Healthcare
    • G&F Precision offers silicone molded parts using world class tooling and process capabilities to healthcare customers for applications in diagnostics, drug-delivery, imaging and endoscopy, angioscopy, arthroscopy and laparoscopy. Catheter tip over-molding, skin contact devices, dental mouthpieces and prosthetics are only a sampling of silicone’s medical utility.
  • Military
    • Silicone is widely used in critical military/aerospace applications because of its flexibility, compression set properties, resistance to temperature changes and biological factors. Eye cups for night vision equipment, seals, switch buttons, and gaskets are just a few of the numerous uses.
  • Electronics
    • The strength, durability and flexibility protects circuit components against contamination for reliable operation and long service life. Silicone extends the service life by providing excellent dielectric behavior and extremely tight sealing properties for buttons, keypads, switch seals, insulators, and more.

Liquid Injection Molding (LIM)
