Latest Patents
Yamaguchi's latest patents include a pipe joint and a manufacturing method for the pipe joint. This innovative pipe joint features a cylindrical hollow with a wall thickness ranging from 2 to 7 mm. The design ensures that the ratio of the length of the hollow in the axial direction (L) to the diameter of the hollow (D) is 5 or less. The pipe joint incorporates a copolymer that contains tetrafluoroethylene and a fluoro(alkyl vinyl ether) unit, with the latter making up 2.8 to 6.0% by mass of the total monomer units. Additionally, the copolymer's melt flow rate at 372° C. is between 4.0 g/10 min and 11.0 g/10 min, while the number of functional groups is capped at 50.
Another significant patent involves an injection-molded body and its production method. This article is produced by injection molding a copolymer that includes tetrafluoroethylene and a fluoro(alkyl vinyl ether) unit. The copolymer's content of the fluoro(alkyl vinyl ether) unit is between 3.5 to 4.7% by mass. The melt flow rate at 372° C. ranges from 22.0 to 35.0 g/10 min, and the number of functional groups is limited to 20 or less per 10 main-chain carbon atoms. The injection molded article is designed with a gate section that corresponds to the mold's gate, ensuring optimal flow characteristics.
