ABRASION-RESISTANT RUBBER ROLL COVER WITH POLYURETHANE COATING

摘要

An industrial roll includes: a substantially cylindrical metallic core; a rubber base layer that is adhered to and circumferentially overlies the core; a rubber top stock layer that circumferentially overlies the base layer; and a polyurethane coating that circumferentially overlies the top stock layer. In this configuration, the roll can provide improved abrasion- resistance, sheet release properties, and/or toughness compared to a roll with a rubber cover, but may provide these properties in a cover that is softer than a typical polyurethane cover.
