  Today's KNOWLEDGE Share Extrusion barrel design has long been constrained by manufacturing limitations as much as by processing requirements. Additive manufacturing changes that equation. By enabling corrosion-resistant super alloys to be applied precisely where the process requires them — at the discharge end, injection ports, or other high-exposure regions — engineers are no longer forced to treat corrosion protection as a uniform requirement along the entire barrel. The implications extend beyond material placement: - Pressure transducers, melt temperature sensors, and injection ports can be positioned where process conditions demand them, not where conventional construction allows - Versatile corrosion-resistant feedstock, independent of barrel diameter or geometry, reduces lead times and procurement complexity - The same manufacturing approach scales across laboratory extruders to large production systems As the article frames it, this represents a shift from designing barre...

Bcomp, a Swiss pioneer in high-performance flax composites, has partnered with Polestar to bring its lightweight bio-based materials into the new Polestar 5 four-door electric grand tourer (GT). The vehicle features Bcomp’s ampliTex™ and powerRibs™ technologies in the front seatbacks and tailgate structure, reducing the use of virgin plastics. The collaboration began during the development of the Polestar Precept, a concept car and evolved into large-scale production for the Polestar 5. Together, the companies developed a bespoke ampliTex flax fabric known as the “Polestar Signature Weave”, designed to serve both structural and aesthetic functions in the interior cabin. This material has since become a defining feature of Polestar’s minimalist and transparent design language, engineered and tested for durability and performance across thousands of cars in global markets. Driving sustainability transparency for the automotive industry: The Polestar 5 carries a cradle-to-gate carbon foot...

Sometimes, the answer is hidden earlier in the process: Pigment dispersion. Pigment dispersion is more than simply mixing pigment into a liquid.

Sicomin has expanded its structural adhesive portfolio with the launch of two new cartridge-based epoxy systems, SR 740 and SR 790. Developed for composite assembly and bonding applications, the new formulations combine controlled, precise application with the mechanical performance required for demanding structural components. Sicomin has expanded its structural adhesive portfolio with the launch of two new cartridge-based epoxy systems, SR 740 and SR 790. Developed for composite assembly and bonding applications, the new formulations combine controlled, precise application with the mechanical performance required for demanding structural components. SR 740 for thick-section structural bonding SR 740 is a structural epoxy adhesive formulated for large bonding areas and high-load assemblies where a thick, non-sag bond line is required. The formulation provides gap-filling capability for joints with bond-line thicknesses of up to 25 mm, allowing it to accommodate dimensional tolerances ...

BASF has received two awards for pilot projects exploring innovative approaches to closing the loop on engineering plastics. The two recycling projects for polyamide 6 (PA6) presented at K 2025 – depolymerization and solvent-based recycling – received both the MATERIALICA Award 2026 (winner in the category “CO2 Efficiency”) and the Fakuma Innovation Award 2026 (2nd place in the category “sustainability”).  The awards recognize the technological progress achieved at pilot scale and the potential of both processes to contribute to closed material loops for demanding automotive applications in the future. Together with Mercedes-Benz, ZF and Pรถppelmann K-TECH, the technologies were successfully demonstrated under pilot conditions on near-production components designed to closely reflect real series applications rather than purely demonstrative parts. Further development and scale-up would be required for industrial-scale implementation. With these two complementary advanced recycling a...
