Antichafing strip for shaving equipment head

摘要

An anti-friction strip for a discardable razor is obtained by extruding a polymer mixture comprising an insoluble polymer material and polyethylene oxide. It has an initial coefficient of dynamic friction (KD) of the order of less of or less than 0.2. The mixture for extrusion includes, as its polyethylene oxide, only a substance whose mean molecular weight is greater than 3.5 million. The strip is preferably obtained by extruding a mixture comprising polystyrene and polyethylene oxide having a molecular having a molecular weight greater than 7 million. The specified anti-friction strip is fixed thereto by ultrasonic welding to a shaving head.
