    摘要： A grease composition is disclosed. The grease composition comprises: 100 parts by mass of (A) an aryl group-containing polyorganosiloxane; 1 to 50 parts by mass of (B) an acrylic block copolymer; and (C) solid particles. Component (B) has a weight average molecular weight of from 10,000 to 1,000,000 and a molecular weight distribution [ratio (Mw/Mn) of weight average molecular weight (Mw) to number average molecular weight (Mn)] of 1.5 or less. Component (B) is present in an amount of from 1 to 40 mass % of the overall grease composition. The grease composition has excellent damping characteristics, hardly any oil separation (even at high temperatures), excellent lubricating performance, and an ability to reduce noise generated by a mechanical device when applied to a noise-generating site of the mechanical device. Sliding members, etc., to which this grease composition has been applied, are also disclosed.

    摘要： A lubricating grease composition for a resin member is used to be supplied as a lubricant on a surface of at least a sliding portion of a resin member including the sliding portion with an other member. The lubricating grease composition for a resin member contains a base oil which is a mixed oil of a poly-α-olefin having a kinetic viscosity at 40° C. of 18 to 50 mm2/s and an ethylene-α-olefin copolymer having a number average molecular weight of 40,000 to 200,000, a lithium-based complex soap as a thickener and a polytetrafluoroethylene resin as a solid lubricant having a mixing ratio of 4 to 12 mass % to the entire lubricating grease composition, wherein the base oil has a kinetic viscosity at 40° C. of 80 to 200 mm2/s and a worked penetration of the lubricating grease composition ranges from 265 to 340.

    摘要： A fluoropolymer composite comprising at least one fluoropolymer and particulate filler material is formed using a slurry process, in which the particulate filler material is first dispersed in a polar organic liquid, which is then combined with a suitable particulate fluoropolymer. The combination is dried to form a composite powder material. The composite powder material, with optional addition of another fluoropolymer, is processed to form a fluoropolymer composite body. The process can be carried out with either melt-processible or non-melt-processible fluoropolymers.

    摘要翻译： 包含至少一种含氟聚合物和颗粒填料的含氟聚合物复合材料是使用浆料法形成的，其中颗粒状填料首先分散在极性有机液体中，然后将其与合适的颗粒状含氟聚合物混合。 将组合物干燥以形成复合粉末材料。 加工另外含氟聚合物的复合粉末材料被加工以形成含氟聚合物复合体。 该方法可以用可熔融加工的或不可熔融加工的含氟聚合物进行。
