Polypropylene Copolymers for Under-the-Hood Applications
Thermal management will become increasingly important in the current development of alternative drive concepts. For this purpose, suppliers to the automotive industry need application-optimised materials. The Hamburg-based plastics distributor K.D. Feddersen relies on Hostacom grades from LyondellBasell with optimised low creep performance.
"For combustion engines, thermal management is already established and ensures the targeted control of the engine temperature depending on the load and operating conditions that occur. It is also of great importance for alternative drive concepts," says Wolfgang Wieth, Director Business Development at K.D. Feddersen GmbH & Co. KG.
In battery-powered electric vehicles, intelligent thermal management improves the possible range, ensures the constant functionality of the battery and can optimise its charging time – even at extreme conditions. Furthermore, the targeted use of high and low temperatures ensures climate comfort in the vehicle interior. Both systems, air conditioning and cooling, will form a common integrated system in the future.

Hostacom Grades from LyondellBasell with Optimised Low Creep Performance
Hostacom grades with optimised low creep performance are polypropylene copolymers (PP copolymers) reinforced with short glass fibres. According to the distributor, these PP compounds show excellent creep resistance compared to standard grades. Therefore, the grades are ideally suited for applications in the engine compartment with coolant contact. With a medium flowability the grades are ideally suited for the substitution of PA 6.6. Concrete application examples are connecting elements of hoses, flanges or housings for electric vehicles.
Hostacom EKG 2087T e.g. is also available as a laser-weldable grade, thus covering a wide range of applications.
