ABSTRACT:
A roll comprising a hollow metal core member, an intermediate base layer or layer, and a polyurethane cover, the intermediate base layer compounded to have improved thermal conductivity. The intermediate base layer or layers having improved thermal conductivity function to dissipate heat generated by hysteresis (deformation energy), thereby permitting the rolls to operate at higher roll speeds and higher pressures without roll failure.
