  • Patent number: 11866568
    Abstract: The present disclosure is directed to a component for a telecommunication apparatus, the component comprising a molded product made of a resin composition. The resin composition comprises (a) a matrix resin and (b) titanium dioxide. The (A) matrix resin comprises (A-a) a polyphenylene ether-based resin. The sum of the contents of the (A-a) polyphenylene ether-based resin, and (A-b) a block copolymer containing at least one block mainly composed of an aromatic vinyl monomer unit and at least one block mainly composed of a conjugated diene monomer unit and/or a hydrogenated product of the block copolymer with respect to 100 parts by mass of the (A) matrix resin is 75 parts by mass or more. The average L/D of the (B) titanium dioxide is 1.2 or more and 6.0 or less, and the content of titanium dioxide having an L/D of greater than 7.0 is less than 10%.

  • Publication number: 20220372283
    Abstract: Provided are a polyamide/polyphenylene ether resin composition that has excellent fluidity, heat resistance, and surface impact strength while also having excellent repeated processability and a shaped product that includes this resin composition. The resin composition contains: (a) a polyamide; (b) a polyphenylene ether; (c) a compatibilizer for the (a) polyamide and the (b) polyphenylene ether; and (d) a polyhydric alcohol including at least two hydroxyl groups and having a number-average molecular weight (Mn) of less than 500. The content of the (d) polyhydric alcohol is 0.3 parts by mass to 5 parts by mass relative to 100 parts by mass, in total, of the (a) polyamide and the (b) polyphenylene ether. A ratio of terminal amino group concentration relative to terminal carboxyl group concentration (terminal amino group concentration/terminal carboxyl group concentration) in the (a) polyamide is 0.3 to 0.5. The (a) polyamide forms a continuous phase.
