    Soft Materials with Recoverable Shape Factors from Extreme Distortion States – Goff et al.

    The new materials reported here are specifically polysiloxanes, derived from high molecular weight uncross-linked polymeric liquids that when formed into nanocomposites demonstrate exceptional elongations (>5000%). These materials are readily manufactured and satisfy the structural requirements for long-term stretchable and implantable devices with integrated fluidics and electronics in soft tissue.  Click here for product information on Gelest xPDMS (PP2-RG09).

    Silicones and Polymers, Applied Technology

    Soft Tissue Compliant Silicones for Medical Devices

    ExSil® silicone nanocomposites exhibit surprising material properties, such as up to 5,000% stretchability with elastic recovery, the ability to resist tear failure (both initiation and propagation), self-healing/sealing behavior and intrinsically low extractables. As a group, these materials demonstrate an ability to resist and recover from conditions that would normally result in the failure of other elastomers.

    Product Resource

    Ultra-high Elongation Silicone Elastomers – Arkles et al.

    Silicone elastomers with elongations approaching 5,000%, nearly four times greater than any other commercial elastomer, are now available. These new elastomers utilize a cure mechanism that generates elastomeric properties by driving linear polymers to extremely high molecular weights with concomitant formation of intra- and inter-chain entanglements, rather than covalent crosslinking.  Click here for product information on Gelest ExSil® 100 (EM2-EX100).
