A rotary foam sanding tool for use with a powered rotary hand tool has a shaft (110) connected to a hub or mandrel (115), an abrasive surface contacting layer (135), a compressive foam layer (130) intermediate the abrasive surface contacting layer and the mandrel. The abrasive surface contacting layer in on the exterior of the tool and is comprised of an abrasive substance. The compressive layer is composed of tubular polyethylene foam that has been treated with a fluorination process that allows the glue to adhere to the surface of the polyethylene foam. The rotary foam sanding tool may also include a mandrel contacting layer (425). The mandrel contacting layer is intermediate the mandrel (415) and the compressive foam layer (430), and the compressive foam layer is intermediate the mandrel contacting layer and the abrasive surface (435). |
