ANTICHAFING STRIP FOR SHAVING EQUIPMENT HEAD AND SHAVING EQUIPMENT HEAD COMPRISING SAME

摘要

The invention concerns an antichafing strip for a disposable shaving equipment obtained by extrusion of a polymer mixture comprising an insoluble polymer material and polyethylene oxide, having an initial dynamic friction coefficient (KD) of the order of or less than 0.2. The mixture to be extruded comprises exclusively, as polyethylene oxide, a product having a molecular weight average higher than 3.5 millions. Preferably, it is obtained by extrusion from a mixture comprising polystyrene and polyethylene oxide having a molecular weight average higher than 4 millions, in particular one single polyethylene with molecular weight average higher than 7 millions. The invention also concerns a shaving equipment head whereon said antichafing strip is fixed by ultrasonic bonding.
