Arkema and Toyobo to Start Alliance on High Temperature Biobased Polyamides

-
COLOMBES CEDEX, France -- Arkema and Toyobo have decided to form a strategic partnership to develop high-temperature polyamides made from renewable resources. Under this collaboration, Arkema and Toyobo will promote a new generation of high-temperature polyamides, with improved technical properties and lower environmental footprint.
The new products initially consist of two ranges with melting points around 250°C and 315°C, with a very low moisture pick up and a biobased content up to 70%. Their unique properties make them particularly suitable for highly technical metal replacement applications in consumer electronics and automotive applications, when high-temperature resistance and dimensional stability are requested and where plastics could not be used before.
Arkema recently launched Rilsan® HT, a flexible HTPA to replace metal and save costs in highly technical automotive applications.

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
