<P>PROBLEM TO BE SOLVED: To provide a partial vacuum brake booster line produced from a polyamide-blend molding material containing a polyamide-blend component and an impact-resistive component. <P>SOLUTION: The polyamide-blend component for the polyamide-blend molding material contains (A) 25 to 65 wt.% of a polyamide being a partial crystalline polyamide exhibiting a fusion enthalpy higher than 40 J/g and composed of polyamide PA11, PA610, PA612, PA1010, PA106, PA106/10T, PA614 and PA618, (B) 0 to 25 wt.% of a polyamide being an amorphous polyamide and/or a microcrystalline polyamide and having a fusion enthalpy of 4 to 40 J/g, (C) 1 to 55 wt.% of a polyamide having 6 carbon atoms, and further (D) 5 to 35 wt.% of a non-polyamide elastomer or a mixture of a non-polyamide elastomer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
