  • Patent number: 11987933
    Abstract: A papermaking device may have excellent strength and suppressed unevenness in strength between its parts. Such a papermaking device may be used in papermaking machine and may include at least one resin layer comprising polyurethane resin. The polyurethane resin may be obtained by reacting a urethane prepolymer having an isocyanate group with a curing agent having an active hydrogen group. The urethane prepolymer may be obtained by reacting a polyisocyanate compound including 2,4-tolylene-diisocyanate and/or 2,6-tolylene-diisocyanate with a polyol compound including one or more polyether polycarbonate diol(s).
