Dow, global leader in materials science, together with Adient, a global manufacturing leader in automotive seating, commercially launched #SPECFLEX™REN , a next-generation #polyurethaneseating solution now available with ISCC PLUS certified bio-attributed* feedstocks enabled via a mass balance approach. “This collaboration underscores Dow’s commitment to advancing sustainable mobility through materials science innovation. By launching SPECFLEX™ REN, we are enabling our partners to integrate renewable feedstocks into the polyurethane seating value chain through an ISCC PLUS certified mass balance approach without compromising performance, supporting their decarbonization goals,” said Selamawit Belli, marketing manager. Polyurethane foams have historically been designed for long-term durability. Through this collaboration, #Dow and #Adient are working together to enable seating solutions while utilizing bio-circular attributed feedstocks, which have a lower carbon footprint compared t...

Researchers at #ColoradoStateUniversity (CSU) have developed a catalytic process that converts #carbondioxide and #bicycloalkane into high-strength, heat-stable, chemically resistant #polyesters with building blocks recoverable at end of life. The work is described in Nature. Why this CO₂-based polyester is different The process uses an organic catalyst to initiate a reaction between carbon dioxide and bicycloalkane, forming new chemical bonds in a durable, customizable synthetic polyester. According to the study, the resulting materials withstand heat stress and chemical exposure, and exhibit both high mechanical strength and flexibility. Performance is tunable: according to first author Min Zhu, the polymers can be designed to match the strength of tough plastics or the softness of rubber depending on formulation.   Carbon dioxide has been explored as a polymer synthesis feedstock since the 1960s, but achieving high CO2 incorporation while producing recyclable, degradable pol...

𝐓𝐨𝐝𝐚𝐲'𝐬 𝐊𝐍𝐎𝐖𝐋𝐄𝐃𝐆𝐄 𝐒𝐡𝐚𝐫𝐞 𝐓𝐡𝐞 𝐒𝐢𝐥𝐞𝐧𝐭 𝐊𝐢𝐥𝐥𝐞𝐫 𝐢𝐧 𝐏𝐔 𝐅𝐨𝐚𝐦: 𝐖𝐚𝐭𝐞𝐫 𝐂𝐨𝐧𝐭𝐞𝐧𝐭 We obsess over the Isocyanate Index, but there's another variable that's just as ruthless: the water content in your formulation. If the water content changes by just 0.1%, it can throw your NCO Index off by a full point. This means your foam can either over-expand and crack, or not rise properly. The consequences are instant and severe: *Too much water? Your foam will over-expand, leading to splits, shrinkage, and a weak, brittle structure. *Too little water? You get poor rise, high density, and a loss of valuable physical properties. I've seen entire batches scrapped because a drum of polyol absorbed moisture from the air in the warehouse. The culprit is often invisible until it's too late. Industry Standards for Water Content: Maintaining precise water content in raw materials is paramount. While specific limits can vary based on applicatio...

The aviation industry faces mounting pressure to reduce weight and improve energy efficiency as it pursues sustainability goals. The #ReCellproject offers a groundbreaking solution: supercapacitors and structural batteries made from #recycledcarbonfiber that store energy while serving as integral aircraft components. Coordinated by #Spanishaerostructures manufacturer #Sofitec , with participation from Aimplas, the Spanish Plastics Technology Centre, and I2CON, the initiative represents a paradigm shift in aeronautical component design through multifunctional materials that combine mechanical properties with energy-storage capacity. Overcoming electrification barriers Transport electrification remains critical for reducing CO₂ emissions, but aviation confronts significant obstacles due to battery weight and energy density limitations. Re-Cell tackles this challenge by developing #structuralcomposites capable of storing energy, eliminating separate systems, and optimizing overall air...
