  • Sanding pad containing a heat distortable polymer and sanding process using same
    Patent number: 5759090
    Abstract: A sanding pad (102, 204) comprising a plate-shaped substrate (104, 201) and an abrasive (103, 203) fixed by the use of a fixing means (102, 202) onto a major surface of the substrate (104, 201), and the substrate (104, 201) having a heat distortable polymer which has a dimension-retaining first state within a normal use temperature range of said pad (102, 204) and a deformable state at a temperature above said normal use temperature range. The invention provides an inexpensive sanding pad capable of sanding a three-dimensional curved surface, uniformly and easily, which is superior in repeated usability.
