How do innovative silicones improve prosthetic liners?

The Challenge

Manufacturers of medical devices and prosthetic liners use soft silicone technologies in their products to improve patient care and comfort. When making prosthetic liners, for example, silicones are essential to create soft and flexible materials that can be rolled over the patient's residual limb for protection and allow the suspension of a prosthetic device. Liners control swelling, avoid skin abrasions and reduce the pain that amputees often experience. These features provide amputees with the flexibility they need to undertake a wide range of tasks, including small and precise movements.

The key challenge in developing these devices is to select materials with two properties that are often incompatible: low durometer levels and optimal mechanical properties like Liquid Silicone Rubber (LSR). Customized silicones can overcome this tradeoff by providing formulations to make single and versatile devices that are easy to fit, comfortable and durable.
