摘要： Embodiments of the invention provide for paper mill equipment that can better withstand the conditions of a paper mill. Embodiments encompass paper mill equipment that incorporate a polyurethane layer having a hysteresis value of less than 70% and a permanent set of less than 30%. The polyurethane layer includes a polyurethane produced by curing a mixed composition. The mixed composition includes at least a urethane prepolymer (A) and at least a curing agent (B) having an active hydrogen group (H). The urethane prepolymer (A) has at least one terminal isocyanate group and is obtained by reacting at least a polyisocyanate compound (a) with at least a polycarbonate diol compound (b) having a number average molecular weight of at least 1500 g/mol. The curing agent (B) includes at least an amine compound. The elastomer compositions are also useful to coat the acid pickling roller in the steel industry.
