Abstract: The present invention relates to a composition for producing a high heat resistance insulating material, and an insulated cable having the same. A composition for producing a high heat resistance insulating material according to the present invention comprises 0.5 to 10 parts by weight of a crosslinking agent based on 100 parts by weight of a fluorine-based rubber. The present invention provides an insulated cable that is capable of sending more electric current at least twice than an allowable current capacity based on a cross-sectional area of a conductor of a conventional cable. Therefore, the present invention can reduce an outer diameter of an insulated cable by 30% or more and the weight by 40% or more in comparison with the conventional cable, and thus provides the insulated cable with lightweight and flexibility.

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.
