Abstract
Disclosed is a tip seal and a seal material for a scroll type compressor with a discharge pressure of 8 MPa or more, comprising a resin composition that is molded into a spiral shape, and that contains an aromatic polyether ketone based resin containing at least 5 to 30% by weight of a carbon fiber and 1 to 30% by weight of a tetrafluoroethylene resin.
Claims11
A spiral shaped tip seal for a scroll type compressor with a discharge pressure of a 8 MPa or more which uses a carbon dioxide gas as a refrigerant, said spiral shaped tip seal comprising a resin composition consisting essentially of,
- an aromatic polyester ketene based resin,
- a carbon fiber, and
- a tetrafluoroethylene resin,
- wherein the resin composition contains 5 to 30% by volume of the carbon fiber to 1 to 30% by volume of the tetrafluoroethylene resin based on the whole resin composition.
A seal material of a resin composition for a scroll type compressor with a discharge pressure of 8 MPa or more which uses carbon dioxide gas as a refrigerant, said resin composition consisting essentially of,
- an aromatic polyether ketone based resin,
- a carbon fiber, and
- a tetrafluoroethylene resin,
- wherein the resin composition contains 5 to 30% by volume of the carbon fiber to 1 to 30% by volume of the tetrafluoroethylene resin based on the whole the resin composition.
A seal material of a resin composition for use in a swash plate type, a rotary type a linear type, or a screw type compressor with a discharge pressure of 8 MPa or more using a carbon dioxide gas a as a refrigerant, said resin composition consisting essentially of,
- an aromatic polyether ketone based resin,
- a carbon fiber, and
- a tetrafluoroethylene resin,
- wherein the resin composition contains 5 to 30% by volume of the carbon fiber to 1 to 30% by volume of the tetrafluoroethylene resin based on the whole resin composition.
