Also provided is a papermaking device for use in papermaking machine, the papermaking device comprising at least one resin layer comprising a polyurethane resin, wherein the polyurethane resin comprises as a component a polyether polycarbonate diol comprising one or more unit(s) A expressed by the following formula (1).
Claims18
A papermaking device for use in papermaking machine,
- comprising at least one resin layer comprising a polyurethane resin, wherein:
- the polyurethane resin comprises as a component of the polyurethane resin a polyether polycarbonate diol consisting essentially of one or more unit(s) A expressed by the following formula (1):
- in the formula (1):
- R1 is a bivalent group derived from a polyether polyol having the number average molecular weight equal to or higher than 200 and equal to or less than 3,000.
A method for producing a papermaking device for use in a papermaking machine,
- comprising a step of forming a resin layer comprising a polyurethane resin by curing a polyurethane material, wherein:
- the polyurethane material comprises as a component of the polyurethane resin a polyether polycarbonate diol consisting essentially of one or more unit(s) A expressed by the following formula (1):
- in the formula (1):
