    摘要： Disclosed is a resin composition for improving a whitening resistance in bending deformation. The flame retardant polypropylene-based resin composition with an improved whitening resistance in bending deformation according to the present invention includes a polypropylene-based resin, a polyolefin elastomer, a modified polyolefin elastomer grafted with polar groups and an inorganic flame retardant, wherein the polypropylene-based resin is included at a content of 5 to 50 % by weight of the total composition, wherein the polyolefin elastomer is included at a content of 0.1 to 50 % by weight of the total composition, wherein the modified polyolefin elastomer grafted with polar groups is included at a content of 0.1 to 30 % by weight of the total composition, and wherein the inorganic flame retardant is included at a content of 30 to 75 % by weight of the total composition. The resin composition according to the present invention may be used as a coating material of electrical wires, and therefore may be useful to minimize a whitening phenomenon in bending deformation without deteriorated physical properties such as tensile strength, tensile elongation, etc.

    摘要： A micro coaxial cable includes an inner conductor; an insulation layer having foaming cells and formed to surround the inner conductor; an over-foaming preventing layer formed to surround the insulation layer for the purpose of uniform forming of the foaming cells; a metal shield layer formed to surround the over-foaming preventing layer; and a protective coating layer formed to surround the metal shield layer. The over-foaming preventing layer restrains abnormal growth of foaming cells formed in the insulation layer such that the foaming cells are successively adjacently formed with uniform size. Due to the uniformity of foaming, the dielectric constant of the insulation layer is not locally different but uniform as a whole, thereby capable of improving transmission characteristics. In addition, the micro coaxial cable enables to transmit signals even at a high frequency transmission of GHz range, which was impossible in the prior art.
