PEEK Spindle Nuts Avoid Malfunctioning of Automotive Plastic Pieces During Accident

-
The BMW Group has approved spindle nuts made from Evonik Industries product VESTAKEEP® polyether ether ketone (PEEK) polymer. The spindle nuts are used in electrical steering column adjustment assemblies. As claimed, the VESTAKEEP® L4000G-based spindle nuts do not break under the severe conditions and thus prevent any plastic pieces from disabling the function of safety-relevant features. With improved ductility, high dimensional stability at different temperatures, chemicals & impact-resistance, VESTAKEEP® PEEK passed the tests by BMW.
VESTAKEEP® spindle nuts are used in the electrical steering column adjustment assemblies that are manufactured by Solingen, Germany-based C. Rob. Hammerstein GmbH & Co. KG. Exceptional material characteristics diversify its future use in mechanical steering column adjustment assemblies, besides automotive and aerospace applications, oil and natural gas sectors, semiconductor, electronics and medical industry and much more.

Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.

Today's KNOWLEDGE Share:High and low shear rate changes in Rheology

-

Today's KNOWLEDGE Share If a relatively high Mw grade flows from thin to thick, as shown in the picture, and if the time needed to fill the thick section is way shorter than the average polymer relaxation time, the polymer will not be able to reach its higher viscosity (corresponding to higher thickness/lower shear-rate). I am assuming here the polymer reached equilibrium low viscosity in the thin section, say for instance because it is much longer. Any pressure prediction not accounting for transient rheology would then overpredict the pressure to fill.Of course the diverging flow will further complicate the situation and mess with the molecular orientation created in the thin section, but to what extent ? Since this is more of a reasonable "conjecture", don't take this for granted, and discuss or share your opinion in the comments. There are hundreds of Rheology papers on the "4:1 contraction flow". Not sure I have ever seen any on the..."1:4 expansio
