  • Publication number: 20230303826
    Abstract: Provided is a resin composition contains, with respect to 100 parts by mass of a thermoplastic resin, 10 to 70 parts by mass of a recycled carbon fiber; and 0.1 to 15 parts by mass of a functional group-containing compound; wherein the recycled carbon fiber is a baked product of a composite of an epoxy resin and a carbon fiber, and comprises 5% by mass or more of a residue derived from the epoxy resin; and an ISO multi-purpose test specimen with a thickness of 4 mm obtained by molding the resin composition has a maximum flexural strength of 130 MPa or more in accordance with ISO 178.

  • Patent number: 9080044
    Abstract: This invention is a rubber stopper for medical treatment, which is obtained by molding a resin composition containing a component (A): at least one of a block copolymer having at least two of a polymer block P containing a vinyl aromatic compound as the core and at least one of a polymer block Q containing a conjugated diene as the core and a hydrogenated block copolymer thereof, a component (B): a hydrocarbon-based softening agent for rubbers, and a component (C): a polyolefin-based resin, wherein the resin composition contains a specified amount of the component (C) based on the total amount of the component (A) and the component (B), and the resin composition has a specified molecular weight distribution.
