    摘要： A durable refrigerant transporting hose is provided which includes a gas barrier layer made of a polyamide resin composition, and prevented from being degraded by the refrigerant or compressor oil. A refrigerant transporting hose 1 including a gas barrier layer 2 made of a polyamide resin composition. The polyamide resin composition contains at least one metal compound selected from the group consisting of hydroxides, oxides and carbonates of divalent and trivalent metals in an amount of 1% to 15% by weight relative to the total amount of the metal compound and the polymer component. An olefin elastomer may be added to the polyamide resin composition to enhance the flexibility and durability.

    摘要： There is provided a rubber track used for an undercarriage of a vehicle, and particularly an improvement in a guide lug which protrudes from an inner peripheral surface of the rubber track. In the rubber track in which a plurality of rubber lugs are formed on an outer peripheral surface of an endless rubber elastic body and a plurality of guide lugs are formed on an inner peripheral surface of the elastic body, the guide lugs being used for transmission of driving force or prevention of detracking between the guide lugs, and track rollers, idlers or sprockets, a heat-resisting thermoplastic resin member having low friction properties, a heat-resisting thermosetting resin member having low friction properties, or a resin member having a Barcol hardness (A type) of 40 degrees or less is exposed at one or more surfaces of each of the guide lugs, the surface or surfaces contacting other member.

    摘要： Disclosed is a guide lug composition for a rubber track comprising 5 to 40 parts by weight of a fatty acid amide based on 100 parts by weight of a raw rubber material; or comprising 5 to 40 parts by weight of a Ultra High Molecular Weight Polyethylene (UHMW-PE) powder based on 100 parts by weight of a raw rubber material; or comprising 5 to 40 parts by weight of a fatty acid amide and 5 to 40 parts by weight of a UHMW-PE power based on 100 parts by weight of a raw rubber material. The guide lug composition serves to reduce abrasion of or damages to a guide lug, to improve the characteristics in preventing the rubber track from slipping off a wheel, which is called “detracking”, to reduce friction loss when the guide lug contacts and collides with the wheel thereby reducing energy losses.
