The present invention provides a lightweight valve resin member that is high strength and can be used in a high temperature atmosphere and is excellent in chemical resistance and corrosion resistance. It is a resin member for valves which molded the molding material of 80 MPa-400 MPa of tensile strength at normal temperature, and the resin member for valves which molded the molding material of 75 MPa-350 MPa of tensile strength at 120 degreeC. Moreover, the polyisocyanate compound (B), hardening | curing agent (C), whose number of isocyanate groups will be 0.1-1.5 with respect to one hydroxyl group of 60-100 epoxy resin (A) and epoxy acrylate resin (A), And it is a resin member for valves which shape | molded the molding material which mix | blended 20-70 mass% of fiber reinforced materials (E) with the resin composition containing internal mold release agent (D).n n n n Resin for Valve, Tensile Strength, Impact Strength |
