𝐓𝐨𝐝𝐚𝐲'𝐬 𝐊𝐍𝐎𝐖𝐋𝐄𝐃𝐆𝐄 𝐒𝐡𝐚𝐫𝐞 𝐋𝐢𝐠𝐧𝐢𝐧-𝐁𝐚𝐬𝐞𝐝 𝐁𝐢𝐨-𝐀𝐝𝐡𝐞𝐬𝐢𝐯𝐞𝐬 𝐟𝐨𝐫 𝐒𝐮𝐬𝐭𝐚𝐢𝐧𝐚𝐛𝐥𝐞 𝐁𝐢𝐨-𝐂𝐨𝐦𝐩𝐨𝐬𝐢𝐭𝐞𝐬 An effective lignin-based bio-adhesive has been developed for use in bio-composites and bio-based materials, offering a sustainable alternative to conventional fossil-derived and formaldehyde-based binders. Lignin, one of the most abundant aromatic biopolymers on Earth, provides a unique combination of natural adhesion, thermal stability, and chemical functionality. By tailoring lignin structure and formulation, I was able to achieve strong interfacial bonding between the particles while maintaining process compatibility with composite manufacturing methods. Key Advantages of the Lignin-Based Bio-Adhesive: • 100% bio-based and renewable • Formaldehyde-free and low-toxicity, supporting safer manufacturing environments • Strong bonding performance in bio-composites • Good thermal stability suitable for hot-pressing and molding pr...

Since its Towpreg development in 2018, the company has established integrated capabilities across the entire value chain—from intermediate material manufacturing to structural design, analysis, filament winding, molding, and finished component production. Kolon Spaceworks first applied its proprietary Towpreg to hydrogen storage tanks for mobility applications, gaining mass-production experience and validating its performance. The technology has since been extended to hydrogen module systems incorporating hydrogen storage vessels. Building on its experience in hydrogen mobility, Kolon Spaceworks expanded the application of its Towpreg technology into the space industry. The company’s proprietary Towpreg has already been applied to key composite components of INNOSPACE’s HANBIT-TLV test launch vehicle. It is also planned for use in the pressure vessel of the SEBIT suborbital test vehicle, as well as the pressure vessel and combustion chamber of the HANBIT-Nano small satellite launch veh...

Today the Commission imposed anti-dumping duties on #imports into the #EU of terephthalic acid from the Republic of Korea and Mexico. The definitive #antidumpingduties imposed on imports from Korea range from 6.1% to 13.3%, while imports from Mexico are subject to a duty of 24.1%. The imposition of the definitive duties follows an investigation which found that imports of #terephthalicacid from #Korea and #Mexico were entering the EU at dumped prices. This is causing injury to the EU’s own industry, which directly employs around 600 people in Belgium, Poland and Spain. Terephthalic acid is a strategic commodity for the EU, because it is a raw material used to produce polyethylene terephthalate. In turn, PET is used to make plastic bottles, food packaging and fabrics – products with a role to play in helping the EU meet its recycling and sustainability targets. The EU market for terephthalic acid is worth some €1.4 billion. source : #Europeancommission

Prestigious #Japanese cosmetics brand KANEBO has selected Eastman Cristal™ One IM812 specialty PET resin for the overcap of its new Generating Essentials Treatment Lotion. “Rooted in KANEBO’s ‘Progress Care’ philosophy and our message, ‘Going beyond beauty, KANEBO heightens hope,’ this lotion reflects our approach to supporting skin through different stages of life rather than focusing on antiaging,” said Shinsuke Magai, KANEBO designer.  For the thick-walled black overcap, KANEBO needed a material that could meet demanding performance and design requirements, especially given the cap’s heavier construction. #CristalOneIM812 met that challenge by passing drop impact testing and maintaining required strength after post-mold painting. Cristal One IM812 delivered the precise aesthetic KANEBO envisioned: a clean, high-quality black with the right gloss and a subtle transition from opaque black to a more transparent black gradient at the top. This combination of toughness, transparency an...

The future of hypersonic manufacturing depends on more than innovative system design - it requires the ability to produce hypersonic composite structures at the speed, quality and scale demanded by today’s national security environment. Today, #AlbanyEngineeredComposites is proud to announce a strategic partnership with #LockheedMartin focused on advancing scalable manufacturing for next-generation hypersonic systems, supporting United States Department of War priorities. At the core of this effort is the ability to translate advanced composite technologies into production-ready, scalable manufacturing processes. Albany’s advanced 3D-woven composite technology provides a critical manufacturing advantage by enabling cost-effective hypersonic missile aeroshells, enabling highly integrated structures, repeatable production and efficient near-net-shape manufacturing. By combining Lockheed Martin’s proven systems integration expertise with Albany’s leadership in advanced composite manufac...

A new labeling technology from #Securikett replaces conventional heat sealing with a secure #labelingsolution . The system combines multiple functions in a single label, offering a solution that is safer, faster, and more cost-efficient than traditional heat-sealing processes. This multifunctional label solution integrates several technologies: structured #adhesivecoatings , built-in VOID technology, precisely applied #siliconecoatings , and custom die-cutting. The interaction of these components creates a packaging solution that unites security, functionality, and regulatory compliance in a single design. The tamper-evident seal immediately indicates if a package has been opened or tampered with, thanks to an integrated #VOIDeffect . At the same time, functional elements such as ventilation holes or viewing windows can be directly incorporated into the label. #Lidlabel with VOID effect and ventilation holes for #tray and cup packaging A key innovation lies in the sealing method: in...

LyondellBasell (LYB) faced exactly these problems on pelletizers driven by 120-hp motors through conventional gear couplings. Gear couplings require regular lubrication and are subject to wear as gear teeth slide during meshing. Flexible-insert couplings carry their own risks, with inserts prone to wear and breakage. The core engineering challenge: any replacement coupling had to accommodate up to 0.690 inches of total axial movement — including shaft retraction for startup, shutdown, and maintenance — without generating axial forces that could overwhelm the hydraulic knife positioning system. Coupling Corporation of America recommended its FLEXXOR coupling, a diaphragm-based design that transmits torque throu...
