▎ 摘  要

NOVELTY - Polyamide molding composition comprises: (A) 32-99.99 wt.% at least one partially crystalline, partially aromatic polyamide; (B) 0-30 wt.% at least one functionalized impact modifier, (C) 0.01-3 wt.% at least one unsubstituted or substituted metallocene, and (D) 0-35 wt.% at least one additive. USE - The composition is used as a filled polyamide molding composition for producing moldings or producing components of the automotive sector, preferably in the engine compartment, electrical, electronics, mechanical engineering, energy production and energy supply, preferably cylinder head covers, engine covers, housings, fastening elements such as clamps, holders, clips , cable ties, dowels or rivets and parts for charge air coolers, charge air cooler flaps, intake pipes, preferably intake manifolds, exhaust pipes, connectors, gear wheels, fan wheels, cooling water boxes, housings or parts of heat exchangers, coolant coolers, thermostats, water pumps, radiators, fastening parts, printed circuit boards, foils, lines, housings and parts of electrical/electronic devices, housings and parts of fan heaters, switches, distributors, relays, resistors, capacitors, coils, lamps, diodes, LEDs, transistors, connectors, regulators, storage and sensors (all claimed). ADVANTAGE - The composition: exhibits improved retention of tear strength and elongation at break, and improved resistance to heat aging, improved flowability; assures longer service lives for thermally stressed components to be achieved or reduces their risk of failure and enables components to be used at higher temperatures; and makes use of heat stabilizers that delay or prevents occurrence of thermo-oxidative damage in components.
