Silicone lubricants

NuSil^® silicone lubricants from Avantor^® offer a wide variety of options to reduce friction and improve performance as well as protect essential medical devices and components. Leading manufacturers worldwide rely on our portfolio of off-the-shelf and custom lubricous silicone solutions, including fluids, greases, dispersions and curable, low coefficient of friction (CoF) coatings. We can customize silicones to meet specific application requirements for lubricity, substrate compatibility, performance characteristics and cure chemistry.

We formulate silicone lubricants that are ideal for a variety of assembly needs:

• Fluids/oils: Available for single and repeated use, NuSil silicone lubricant fluids and oils are offered in a range of standard viscosities as well as options suitable for various substrates.
• Greases: From providing a clean seal between parts under vacuum to offering long-lasting lubrication, our silicone greases provide thixotropic formulations that exhibit little or no migration.
• Dispersions: Lubricants can be blended with a carrier solvent to lower viscosity for ease of application, creating a thin, more uniform layer of lubrication.
• Self-lubricating elastomers: These silicones reduce the number of processing steps to accomplish lubrication of a molded device or component in medical applications. The lubricity is built into the silicone elastomer system and elutes out over time, yielding a lubricious surface on the molded component.
• Low CoF coatings: Our “dry,” curable coatings offer a durable, non-migrating solution to significantly reduce surface tack, blocking and particulate accumulation.
