Abstract

Cleaning blades are made from a modified polyurethane rubber which reduces friction and enables them to be used in an edge-on contact mode without tucking and with a reduced need for external lubricants. The polyurethane rubber is copolymerized with hy droxyl terminated polydim et hylsiloxane oligom ers. These materials are used to substitute for a portion of the polyester used to react with the isocyanate urethane. The level of addition is increased to achieve an optimum between lubrication and mechanical life.
