Abstract:
1. A polymeric composition useful as an electrical conduit covering, consisting of: 100 parts by weight of a base polymer containing a polyolefin polymer; 2 to 45 parts by weight of a polyamide, based on 100 parts by weight of the base polymer, wherein the polyamide is a copolymer of polyamide 6 and polyamide 66 and has melting point equal to or lower than 190° C.; and 70 to 90 parts by weight of a metal hydroxide, based on 100 parts by weight of the base polymer, wherein the composition is flame-retardant composition; wherein the polyolefin polymer consists of polypropylene polymer and ethylene-propylene rubber; wherein the polypropylene polymer consists of homo-polypropylene and maleic acid-modified homo-polypropylene; wherein the homo-polypropylene and the maleic acid-modified homo-polypropylene are blended in a ratio of from 5:1 to 3:2; and wherein an average particle diameter of the metal hydroxide is from 0.1 μm to 20 μm.
