Zusammenfassung: | To provide a resin composition for a chip seal which enables formation of an injection molded article having good heat resistance and abrasive resistance even if rotation speed of a scroll member is higher than conventional rotation speed, and has good moldability by injection molding of a thin and long chip seal, and a chip seal for a scroll type refrigerant compressor which is an injection molding of the resin composition for the chip seal.SOLUTION: A resin composition for a chip seal contains 70 to 90 wt.% of a polyether ether ketone resin, and 2 to 20 wt.% of an inorganic filler having Mohs hardness of 4 or more and thermal conductivity of 60 [W/m K] or less, and a solid lubricant and carbon fibers as remainders.SELECTED DRAWING: Figure 1
【課題】スクロール部材の回転速度が従来より大きい場合であっても、良好な耐熱性、耐摩耗性を有する射出成形物を形成可能であると同時に、薄肉で長尺のチップシールの射出成形による成形性が良好なチップシール用樹脂組成物、及び、当該チップシール用樹脂組成物の射出成形物であるスクロール型冷媒圧縮機用チップシールを提供すること。【解決手段】ポリエーテルエーテルケトン樹脂を70~90重量%、モース硬度4以上且つ熱伝導率60[W/m・K]以下の無機充填剤を2~20重量%、残部に固体潤滑剤と炭素繊維を含むチップシール用樹脂組成物。【選択図】図1 |
