Anti friction strip extruded to the head of barbeamento and head of barbeamento containing such strip

摘要

b take anti friction extruded for the head of barbeamento and head of barbeamento containing such get d take anti friction for disposable razor of the invention is obtained by extruding the PARtir a blend of polymers comprising a polymeric material insoluble and polyethylene oxide. She has a coefficient of mode dynamic (K ~ d ~) of the initial order of or less than 0.2.The mixture extrusar comprises exclusively, such as polyethylene oxide, a product which has an average molecular weight exceeding 3,5 million.Preferably, it is obtained by extrusion from a mixture comprising polystyrene and polyethylene oxide with an average molecular weight of more than 4 million,Remarkably, a polyethylene oxide having a molecular weight of more than 7 million.The invention also refers to a barbeamento head on which is fixed by welding with ultrasound to take anti - friction referred to above.
