  • Publication number: 20210008860
    Abstract: A packing member which effectively prevents the liquid repellent material from peeling off the surface and which is provided with the surface excellent in liquid repellency without the need of executing any particular means such as surface-roughening work, treatment with a plasma or vapor deposition. The packing member is characterized by having a surface layer of a blend of a base material polymer mixed with a fluorine-containing polymer, the surface layer forming a gradient of fluorine atom concentration in which fluorine atoms are more distributed in the surface than in the interior.

  • Patent number: 10737835
    Abstract: A plastic molded body has a surface including a non-fluororesin and a rough surface formed on the surface, in which a fluorine atom is incorporated into the molecular chain of a non-fluororesin forming the rough surface. The molded body maintains excellent liquid repellency for a long period of time and exhibits the same levels of drainage and liquid drop-off properties as the initial levels even when it is brought into contact with a liquid repeatedly.

  • Patent number: 9211672
    Abstract: An apparatus for molding a thermoplastic resin product includes a heating apparatus which conducts heating by radiation of infrared rays by using a light source; a stamper which is radiation heated by infrared rays radiated from the light source; a cooling member which cools the stamper by contacting the stamper which is radiation heated; a first mold which holds the stamper and/or the cooling member in a movable manner, thereby enabling the stamper and the cooling member to be in contact with or remote from with each other; and a second mold which holds a thermoplastic resin to which a structure of a shape-forming surface of the stamper is transferred. The stamper is radiation heated at least in the state where it is remote from the cooling member.
