PROBLEM TO BE SOLVED: To provide a hulling roll having a rubber composition excellent in durability and water resistance.SOLUTION: A hulling roll comprises: a core part; and a rubber layer laminated on the outer circumference of said core part. Said rubber layer is made of a hardened material of a thermo-set urethane composite containing a polyol component, an isocyanate component, a crosslinking agent and silicone oil. Said isocyanate component is TDI and/or MDI. Said silicon oil has a kinematic viscosity 10 to 3000 mm/s at 25°C, and the content of said silicone oil in said thermosetting urethane composition is 0.3 to 10.0 weight% with respect to the total amount of the polyol component, the isocyanate component and the crosslinking agent.SELECTED DRAWING: Figure 1 |
