Abstract: A partial vacuum brake booster line is produced from a polyamide blend molding compound having a polyamide blend component and an impact resistance component. The polyamide blend component of the polyamide blend molding compound comprises the following polyamides: (A) 25 to 65 wt.-% of at least one partially crystalline polyamide having a melt enthalpy of >40 J/g and having an average of at least 8 C atoms per monomer unit, selected from a group which consists of the polyamides PA 11, PA 610, PA 612, PA 1010, PA 106, PA 106/10T, PA 614, and PA 618; (B) 0 to 25 wt.-% of at least one amorphous and/or microcrystalline polyamide, the microcrystalline polyamide having a melt enthalpy in the range from 4 to 40 J/g; and (C) 1 to 55 wt.-% of at least one polyamide having an average of at most 6 C atoms per monomer unit. The impact resistance component is formed from: (D) 5 to 35 wt.-% of a non-polyamide elastomer or of a mixture of non-polyamide elastomers. All specifications in wt.
