  "patent_number": "US 12735562",
  "country": "US",
  "title": "A New Fluoropolymer for Stronger Wires and Molded Parts",
  "original_title": "Copolymer, injection molded body, member to be compressed, and covered wire",
  "summary": "This patent describes a specific type of plastic, a copolymer made with tetrafluoroethylene and perfluoro(propyl vinyl ether), designed to be easily molded and used in things like electrical wires and compressed parts, thanks to its precise chemical makeup and properties.",
  "what_it_does": "The patent describes a special plastic called a copolymer. This plastic is made from two main ingredients: tetrafluoroethylene and a small amount of perfluoro(propyl vinyl ether). The key is the exact amount of the perfluoro(propyl vinyl ether) unit, which is between 2.8% and 3.5% by mass of all the monomer units. It also has a specific \"melt flow rate\" of 31 to 38 g/10 min, meaning it flows easily when melted for manufacturing. Another important feature is that it has very few \"functional groups\" (50 or less per 10^6 main-chain carbon atoms), which are special chemical bits that can affect how the plastic behaves. This specific combination of properties makes it suitable for injection molded items, parts that need to be compressed, and coatings for electrical wires. For example, this material could be used to create the tough, heat-resistant insulation around a high-performance electrical cable in an airplane.",
  "what_it_does_not_cover": [
    "Does not cover copolymers where the perfluoro(propyl vinyl ether) unit content is outside the specific range of 2.8 to 3.5% by mass.",
    "Does not cover copolymers with a melt flow rate below 31 g/10 min or above 38 g/10 min.",
    "Does not cover copolymers having more than 50 functional groups per 10^6 main-chain carbon atoms.",
    "Does not cover copolymers with more than 50 of the specific functional groups listed (e.g., -CF=CF2, -CF2H) per 10^6 main-chain carbon atoms.",
    "Does not cover general fluoropolymers without these precise compositional and physical property limits.",
    "Does not cover materials not intended for injection molding, compression, or wire coating applications."

  "abstract": "A copolymer containing tetrafluoroethylene unit and a perfluoro(propyl vinyl ether) unit, wherein the copolymer has a content of the perfluoro(propyl vinyl ether) unit of 2.8 to 3.5% by mass with respect to the whole of the monomer units, a melt flow rate of 31 to 38 g/10 min, and the number of functional groups of 50 or less per 10 6  main-chain carbon atoms, and the number of functional groups of —CF═CF 2 , —CF 2 H, —COF, —COOH, —COOCH 3 , —CONH 2  and —CH 2 OH of 50 or less per 10 6  main-chain carbon atoms. Also disclosed is an injection molded article, a member to be compressed and a coated electric wire including the copolymer.",
