To provide a light-weight resin member, for a valve, which has high strength and can be used in a high-temperature atmosphere, and is also excellent in chemical resistance and corrosion resistance.
A resin member for a valve, which is produced by molding a molding material having a tensile strength of 80 to 400 MPa at normal temperature, and a resin member for a valve, which is produced by molding a molding material having a tensile strength of 75 to 350 MPa at 120°C are disclosed. There is also disclosed a resin member for a valve, which is produced by molding a molding material comprising a resin composition containing an epoxy acrylate resin (A) having a hydroxyl value of 60 to 100, a polyisocyanate compound (B) having 0.1 to 1.5 isocyanate groups per one hydroxyl group of the epoxy acrylate resin (A), a curing agent (C) and an internal mold release agent (D), and 20 to 70% by weight of a fiber reinforcing material (E).
