Combining Comfort with Durability to Optimize Prosthetic Performance
The cushioning effects, form definition and life-like feel of silicones, make them ideal materials for prosthetic devices such as liners, artificial limbs and pressure relief cushions.
Elkem Silicones offers a full range of Silbione® soft silicone technologies that combine comfort with high mechanical properties for producing a variety of devices for the prosthetic market.
Silbione® Products for Prosthetic Liners and Life-Like Prosthetic Skin:
For prosthetic liners, Silbione® soft RTV, HCR and LSR technologies offer exceptional comfort and high elongation to allow comfortable freedom of movement. For textile liners, Silbione® glue RTV 4418 ADH provides strong adhesion between the textile and Silbione® silicone RTV. Combined with flow aid Additive 11013, application is easy with no soaking through the textile.
