Abstract

The invention relates to a thermoplastic component and to the use thereof in a cooling circuit, in particular in the automotive sector, said thermoplastic component comprising polycaprolactam and polypropylene.

Description

technical field [0001] The invention relates to a thermoplastic component comprising polycaprolactam and polypropylene and its use in cooling circuits, in particular in the automotive sector. Background technique [0002] Polyamide-based polymers are mostly chosen in components of the cooling circuit, where it is desired in certain areas of application that the components are not susceptible to hydrolytic degradation even at temperatures above 100° C. This is especially important in the case of direct contact with the cooling medium. [0003] In this context, the term "hydrolytic degradation" is understood by the person skilled in the art as the cleavage of the amide groups present in the polymer chain under the action of water, which is accompanied by a significant reduction in the properties of the polymer, in particular the material and thus Mechanical properties of the fabricated components. The term "glycolysis" is also often used for components in automotive cooling ...
