ケーブル及びシース層用組成物
Document Type and Number:
Japanese Patent JP6649815
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cable having sufficient flexibility and together therewith, having excellent insulation property and abrasion resistance.SOLUTION: The cable according to an aspect of the invention has one or a plurality of insulation wire and a sheath layer surrounding these insulation wires, and in which Asker A hardness of the sheath layer is 75 or less, load by an abrasion ring test machine is 5 kgf, abrasion depth when rotated 750 times under a condition of 60 rotations per minute is 3 mm or less and volume resistivity is 1.0×10Ω cm or more. The sheath layer has a rubber component and a plurality of inorganic filler existing in the rubber component, the rubber component contains chloroprene rubber as a main component and the inorganic filler preferably contains carbon black and heavy calcium carbonate. The content of the heavy calcium carbonate is preferably 30 pts.mass to 80 pts.mass based on 100 pts.mass of the rubber component. The inorganic filler preferably contains a laminar filler.SELECTED DRAWING: Figure 1
