Thermoplastic molding compounds which have high cold impact strength. The molding compounds are comprised of (i) a polyamide 1012 with a relative viscosity in the range of 1.5-3.0; and (ii) a plasticizer in the amount 2-25 wt. % based on the weight of the polyamide. The inventive molding compounds enable manufacture of molded pieces.

Thermoplastic molding compounds which have impact strength when cold

Polyamide plastic fuel lines which are dimensionally stable and resistant to fuels, alcoholic fuels and alcohols as fuels are prepared from aliphatic high molecular weight polyamides. The fuel lines are prepared by extruding a hot melt of the polyamide, sizing through a die having a diameter in excess of the given diameter of the fuel line, cooling the fuel line in a cooling bath, removing the fuel line from the bath and sizing the fuel line adiabatically through a disk having a diameter less than the given diameter.
