摘要： A cable includes a sheath, and a coating film covering a circumference of the sheath, the coating film adhering to the sheath. The coating film is formed from a rubber composition including a rubber component and fine particles. A static friction coefficient on a surface of the coating film is 0.5 or less. When the coating film is subjected to a testing such that a long fiber non-woven fabric including cotton linters including an alcohol for disinfection with a length of 50 mm along a wiping direction is brought contiguous to the surface of the coating film at a shearing stress of 2×10−3 MPa to 4×10−3 MPa, followed by wiping off the surface of the coating film at a speed of 80 times/min to 120 times/min and 20,000 repetitions thereof for a wiping direction length of 150 mm, a difference (an absolute value of a difference) between the static friction coefficients of the coating film before and after the testing is not greater than 0.1.

摘要： A coating film is provided in a cable, a medical hollow tube, a molded article and a hollow tube. The coating film is formed from a rubber composition including a rubber component and fine particles. A static friction coefficient on a surface of the coating film is 0.5 or less. When the coating film is subjected to a testing such that a long fiber non-woven fabric including cotton linters including an alcohol for disinfection with a length of 50 mm along a wiping direction is brought contiguous to the surface of the coating film at a shearing stress of 2×10−3 MPa to 4×10−3 MPa, followed by wiping off the surface of the coating film at a speed of 80 times/min to 120 times/min and 20,000 repetitions thereof for a wiping direction length of 150 mm, a difference (an absolute value of a difference) between the static friction coefficients of the coating film before and after the testing is not greater than 0.1.

摘要： A cable includes a sheath, and a coating film covering a circumference of the sheath. The coating film adheres to the sheath. The static friction coefficient of a surface of the coating film is smaller than the static friction coefficient of a surface of the sheath. The adhesion strength between the sheath and the coating film is 0.30 MPa or more.

摘要： A cable includes a silicone rubber coating including microparticles and cavities as an outermost coating. A medial hollow tube includes a silicone rubber coating including microparticles and cavities as an outermost coating or an innermost coating. The microparticles may be at least one kind of microparticle selected from silicone resin microparticle, silicone rubber microparticle and silica microparticle. The microparticles may have hardness higher than a hardness of silicone rubber constituting the silicone rubber coating.
