Alpha® Silicone Progressive Liner

Alpha Silicone utilises a platinum-cured medical grade silicone designed for comfort and performance. These highly durable liners provide a high level of protection and excellent tissue stability. A unique blend of vitamin E and mineral oils promotes skin repair and protection, providing a non-greasy and non-tacky interface for the user.

Features and benefits

  • Low flow prevents silicone migrating away from sensitive areas
  • High rebound maintains original shape for increased durability
  • Suitable for medium to high activity users
  • Unidirectional stretch – eliminates pistoning without a distal matrix
  • Multidirectional stretch – reduces shear over patella
  • Increased durability
  • Can accommodate volume fluctuations
  • Compatible with elevated vaccum

Measuring Guide

Ensure accurate measurements at 4cm and 30cm from the distal end to determine the most appropriate liner for the user.

Progressive Profile

The progressive profile provides the ideal combination of thick gel for sensitive areas, and thin gel for movement and donning.

  • 9mm thick distal end
  • 6mm along tibial crest
  • 2.5mm posterior to knee
  • 2.5mm circumferentially at proximal end

Select Fabric with panel

The Select fabric is WillowWood’s most durable and comfortable offering. By combining two distinct materials, it offers support, compression and flexibility. To prevent pistoning, the majority of the fabric has unidirectional stretch, meaning a distal matrix is not required. This allows easy donning and accommodation of volume changes without the need for a new liner. To reduce shear stress over the patella, there is a multidirectional stretch panel over the knee which improves comfort in flexion.

Accordion Umbrella

The accordion umbrella increases socket comfort by conforming to the shape of the underlying residuum, reducing stress and providing a more uniform pressure distribution. The umbrella size corelates to the liner size, meaning equal comfort and conformity across all sizes.
