Elastomer combines ultra-soft touch with robust physical properties

September 01, 2009

A new “ultra-soft” elastomer reportedly offers the healthcare and pharmaceutical industries a feel similar to a firm gel but with greater physical properties, providing a product ideal for potting, encapsulating, or molding devices. MED-4286 from NuSil Technology LLC (Carpinteria, CA) is a pliable silicone elastomer designed for applications requiring low “000” durometer, as well as low modulus and high elongation. The material has a low, pourable viscosity and 12-hour work time. Designated as Unrestricted, MED-4286 can also be considered for use in long-term implants—or those implanted 29 days or longer.

NuSil Technology says its new low-durometer MED-4286 elastomer is ideal for applications requiring a soft, flexible, moldable elastomer.

Brian Nash, VP of marketing and sales at Nusil, said the material serves applications that require “a soft, yet moldable material that can keep its form.” MED-4286 has a one-to-one mix ratio and is packaged in a side-by-side kit for easier use. For implants of less than 29 days or applications that come in contact with body fluid and/or skin, NuSil offers a restricted version of MED-4286. [email protected]
