摘要： The industrial roll of the present invention comprises a substantially cylindrical core, an adhesive layer overlying the core, and a cover overlying the adhesive layer. The cover comprises: a polymeric base layer overlying the adhesive layer; and a top stock layer overlying the base layer. The top stock layer comprises a mixture of an elastomeric material and ultra high molecular weight polyethylene (UHMWPE), with the mixture including 100 parts elastomeric material by weight and between about 25 and 50 parts UHMWPE by weight. With these components in the recited ratios, the roll can be formulated to a desired hardness within the desired 10 to 50 P&J hardness range while maintaining release properties suitable for papermaking in the papermaking environment.
