摘要

polyamide blend molding compound, method of producing a polyamide blend molding compound, and molded part. A first variant of the polyamide blend molding compound comprising a polyamide blend content and at least one impact resistant component is characterized in that the polyamide blend content comprises the following polyamides: (a) 20 to 65% by weight of at least one semicrystalline polyamide with a fusion enthalpy 40 µg and g with an average of 8 carbon atoms per monomeric unit; (b) 8 to 25% by weight of at least one amorphous and / or microcrystalline polyamide, with the microcrystalline polyamide having a melt enthalpy in the range of 4 to 40 µg / g, and (c) 1 to 20% by weight of at least one polyamide with an average of at most 6 carbon atoms per monomer unit. The impact resistant component of such a polyamide blend molding compound comprises the following: (d) 10 to 40% by weight of a polyamide elastomer which is composed of hard segments and soft segments, with the hard segments being based on in lactams and / or aminocarboxylic acids; and (e) 35 wt.% of a non-polyamide elastomer. all details by weight percent with respect to the total weight of the polyamide blend molding compound and result in 100% by weight, optionally supplemented by commercial additives which are also added. Molded parts made of such polyamide blend molding compound such as brake booster lines have a modulus of elasticity of no more than 2400 mpa at a temperature of -40 198 c. the same molded parts have a modulus of elasticity of at least 180 mpa at a temperature of sym 120 198 c.
