摘要： The invention relates to razors and razor blade cartridges and methods of manufacture therefore including at least one razor blade housing made from polymer material and at least one skin contacting surface, the at least one skin contacting surface being made of a superhydrophillic polymer material. The polymer material has surface properties modified by functionalisation. Preferably the polymer material is a TPU or TPE, with a Rockwell hardness D scale between 30 D and 85 D, a tensile strength between 35 and 80 MPA and a flexural modulas between 40 and 2350 MPA The invention also relates to a method of manufacture of a razor blade cartridge including the steps of moulding a cartridge housing including skin contacting surfaces of polymeric material; subsequently activating the skin engaging surfaces of the polymer using either physical or chemical means to make the surface receptive to the covalent grafting of a monomer, and grafting a functional group onto the surface such as an N-vinyl lactam.
