  • Patent number: 6828375
    Abstract: Disclosed is an electrically conductive polyamide resin composition, which is advantageous in light of very excellent flexibility and flowability, suitable for use in extrusion and injection components for motor vehicles requiring impact resistance and electroconductivity. The polyamide resin composition comprises (a) 40-70% by weight of semi-crystalline polyamide resin, (b) 15-40% by weight of thermoplastic elastomer grafted with 0.5-2.0% by weight of maleic anhydride, (c) 9-20% by weight of carbon black powder, (d) 1-10% by weight of sulfonamide based material, and (e) 0.001-0.02% by weight of dicarboxyl based material.

  • Publication number: 20020099136
    Abstract: The present invention is related to a polyamide resin composition having an excellent gasoline resistance and impact resistance at a low temperature, and more particularly, to the polyamide resin composition comprising a general polyamide resin as an active ingredient; an impact modifier for dispersion such as EPM (ethylene/propylene) rubber, EPR (ethylene/propylene rubber) and EPDM (ethylene/propylene/diene) rubber; a plasticizer for providing flexibility such as lactams and sulfonamides; a thickener for uniform processability; and an ionomer for improving the appearance, elongation and impact strength, thus exhibiting advantages over conventional polyamide resins reinforced with an elastomer in excellent flexibility and appearance; superior gasoline resistance and impact resistance at a low temperature; better price as compared to its functions and thus enabling to be used in fuel tube systems of an automobile.
