At a glance
- Long lasting elasticity
- Good skin adhesion
- Good skin tolerance
- Good moisture absorption
Residual limb bedding is an important factor in the quality of a prosthesis. Not only the fit and design of the socket are essential for wearer comfort, but also the materials used. For manufacturing sockets, Otto Bock offers different variants to facilitate matching to the individual features of users.
In today's provision of fittings for persons with physical disabilities, innovative materials for orthopaedic applications have become daily routine. Polytol® is one of these innovative materials. The laminated, flexible inner socket made of this PU resin is a new alternative to flexible inner sockets made of thermoplastic or silicone, or to laminated sockets made of Orthocryl®.
The innovative polyurethane lamination resin system Polytol® is a colourless, transparent, high-quality polyurethane-based three-component resin. Prosthetic sockets made of this aliphatic PU lamination resin system are skin-friendly and are noted for their long lasting elasticity in the defined areas compared to acrylic and epoxy resins. Because of its chemical composition, our PU resin is particularly suitable for lamination work dealing with the production of flexible prosthetic sockets.
Field of application
Polytol® is used for the manufacturing of flexible inner sockets for prostheses. The laminated, flexible inner socket made of Polytol® is an alternative to flexible inner sockets made of thermoplastic or silicone, or laminated sockets made of Orthocryl®. PU resin is particularly well suited for the prosthetic fitting of transfemoral amputees with short residual limbs (max. residual limb length approx. 15cm).
Properties
- Polytol® is a high-quality, colourless, transparent, polyurethane-based three-component resin.
- Polytol® is permanently elastic and provides good adhesion to the skin.
- In defined areas, Polytol® has a higher permanent elasticity than acrylic resins.
- Polytol® contains no irritating or allergenic components. Polytol® is suitable for applications to the surface of healthy skin (no open wounds).
iF material award 2009 for Polytol® PU resin kit
The Polytol® PU resin kit from Otto Bock was awarded the iF material award 2009. In prosthetics, the Polytol® PU resin kit is used to fabricate flexible inner sockets. It is skin-friendly and features high permanent elasticity.
The jury evaluated a total of 98 entries from 13 countries for the iF material award 2009 according to the criteria of material selection, processing, innovativeness, environmental compatibility, design quality, functionality, ergonomics and safety. Five entries received the coveted iF gold award. Whether the Polytol® PU resin kit from Otto Bock also received the gold award will be announced at the awards ceremony on April 20, 2009 at the Hanover trade fair. This is where the Polytol® PU resin kit will be on display from April 20 to 24, 2009 as part of the “material TRENDS” special exhibition.
