The modern limb prostheses can provide entire activity range. They suit for running, swimming, and other physical loads. Some prostheses kinds completely follow the foot shape, and don’t differ from the healthy limbs on their appearance.
The prostheses must effectively provide push function, withstand loads, and have a long-term service lifetime.
The artificial feet with hydraulic ankle control system have been enjoying popularity. They provide resistance on uneven and inclined surfaces, natural foot position at sitting, accurate reproduction of the anatomical limb motion at moving
MODENGY 1014 and MODENGY 1066 anti-friction solid-film coatings are applied onto the hydraulic units of feet prostheses. They provide friction coefficient reduction and stabilization in the rubber-to-metal pairs, joint tightness, and its service lifetime extension. These materials have anti-corrosive properties, and high wear resistance at dynamic loads.
The coatings form a thin dry film containing polytetrafluorethylene, molybdenum disulfide, and graphite in its composition on the surface of the metal parts. This gives them dark grey colour.
The specified MODENGY products cure at heating. After polymerization, they neither make the parts dirty nor emit toxic evaporations.
Use of MODENGY anti-friction solid-film coatings to treat hydraulic units of the feet prostheses provides extending service lifetime and smooth operation of the mechanisms. The materials retain their properties for the entire service life of the prosthesis.
