Abstract
A conductive polyamide resin composition containing 6-15 parts of conductive carbon black and 0.3-5 parts of secondary aromatic amines for 100 parts by weight of polyamide resins is excellent in formability and a tube manufactured using the composition is excellent in conductivity, heat-aging resistance and oxygenated-gasoline resistance as well.
Claims8
A conductive resin tube comprising one or more layers, wherein at least the most inner layer of the said tube comprising a conductive polyamide resin composition containing from 6 to 15 parts by weight of conductive carbon black and from 0.3 to 5 parts by weight of secondary aromatic amine for 100 parts by weight of a polyamide resin.
A conductive resin tube structure comprising a single- or multi-layer conductive resin tube and a protective member disposed partially or totally on the outer peripheral surface of the tube, at least the most inner layer of the said tube comprising a conductive polyamide resin composition containing from 6 to 15 parts by weight of conductive carbon black and from 0.3 to 5 parts by weight of secondary aromatic amine for 100 parts by weight of a polyamide resin.
