Abstract: 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.

Abstract: Recovery times of flexible polyurethane foams are increased by treatment with a pressure sensitive adhesive. An emulsion or dispersion of the adhesive in an aqueous carrier liquid is impregnated into the foam, with subsequent removal of the carrier. This invention is of special interest when the glass transition temperature of the starting foam is 16° C. or lower.
