Abstract
Official abstract text for this publication.
The invention relates to an orthopedic cushion made from a filled elastomer or softened thermoplastics and can be provided with a thin friction-reducing coating made from a non-polar, non-hydrophilic slip-increasing polymer coating namely poly(para-xylene). According to the invention, the above can be achieved by means of a method in which the polymerized polyurethane cushion is subjected to at least one pretreatment step in which volatile components are removed to such an extent as to be able to be immediately coated.
First claim
