Abstract: Disclosed is a polypropylene resin composition with flame retardance and abrasion resistance. The polypropylene resin composition according to the present invention includes 20 to 200 parts by weight of an inorganic flame retardant; and 0.1 to 10 parts by weight of at least one additive, based on 100 parts by weight of a base resin comprising 30 to 90% by weight of polypropylene copolymer resin and 10 to 70% by weight of polyolefin alpha copolymer resin. The polypropylene resin composition according to the present invention can be used for industrial cables with potent endurance since it includes an inorganic flame retardant to show flame retardance and it can remove or reduce a whitening phenomenon and show a significantly improved abrasion resistance without deteriorating moldability or mechanical property even when the contents of the composition are varied to enhance abrasion resistance.

Abstract: 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.

Abstract: 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.

Abstract: An optical cable having a metal tube receiving an optical fiber and bent to form a waved shape is disclosed. The optical cable may prevent cutoff of the optical fiber or deterioration of optical characteristics though tensile force is applied to the optical cable in its longitudinal direction since the metal is formed in a waved shape. To bend the metal tube, the metal tube is passed through roller pair(s) which are shaken in a direction perpendicular to the advancing direction of the metal tube. Thus, it is possible to obtain excess fiber length (EFL) easily and accurately as desired.
