ABSTRACT:
A supporting base material for a tufted rotary finishing pad utilizes a three-layer laminate including an outer face layer of a crosslinked ionomer resin of ethylene and methacrylic acid copolymers reacted with a metal salt, an intermediate layer of an open polyester mesh, and an inner face layer of a non-woven polyester fiber. The tufted fiber finishing media is attached to the crosslinked ionomer resin face of the laminated base which is preferably heat formed to provide a curved pad edge. The base is extremely tough and durable, provides excellent shape retention, resistance to moisture, and resistance to fiber tear-out.
