The requirements for long-term resistance to cyclic mechanical loads, also known as fatigue strength, are increasing, particularly in the case of plastic components found under car hoods. Responding to this trend, Lanxess is building a new polyamide 6 product range dubbed Durethan Performance.
The grades are reportedly several times more resistant to fatigue under pulsating loads than standard products with the same glass fiber content. The first products in the range are the thermally-stabilized Durethan BKV30PH2.0, BKV35PH2.0, and BKV40PH2.0 compounds with glass fiber contents of 30, 35, and 40 percent, as well as the impact resistance-modified Durethan BKV130P compound, which is reinforced with 30 percent glass fiber.
“With these new products, we are targeting applications in automobiles, such as air-intake systems and oil-filter modules or parking brakes. There is also great application potential for housing and structural components of power tools, such as drilling or grinding machines. And with regard to the furniture industry, for example, parts for furniture locking systems could be manufactured from the impact-resistant modified product type,” explains Dr. Thomas Linder, an expert in materials development of Durethan at LANXESS.
