RUBBER COMPOSITION FOR REFRIGERANT-TRANSPORTING HOSE AND REFRIGERANT-TRANSPORTING HOSE
First Claim
1. A rubber composition for a refrigerant-transporting hose comprising at least an inner tube and a reinforcing layer disposed outward of the inner tube, wherein the rubber composition is used for manufacture of the inner tube, the rubber composition comprising:
- butyl rubber;
a scale-like filler; and
carbon black;
an iodine adsorption number of the carbon black being from 65 to 150 mg/g;
a content of the scale-like filler being 20 parts by mass or greater, per 100 parts by mass of the butyl rubber; and
a content of the carbon black being 20 parts by mass or greater and less than 50 parts by mass, per 100 parts by mass of the butyl rubber.
