  From field to sustainable products The airlay technology – from high-performance fibers to technical nonwovens In a world increasingly focused on sustainability, #naturalfibers are stepping into the spotlight. #Bastfibers such as #hemp , jute, and #flax are no longer niche, they are becoming essential in automotive, construction, and technical nonwoven applications. Their appeal lies in sustainability, but their variability in length, cleanliness, and moisture content demands advanced processing solutions. #ANDRITZ has combined decades of expertise with innovative bast fiber processes and airlay technology to deliver a complete, integrated approach for natural nonwovens and technical textiles – all under one roof. The bast fiber process – from straw to high-performance fibers ANDRITZ bast fiber processes enable a sustainable journey from agricultural straw to high-performance fibers. Processing begins with dry cleaning, decortication, and refining, removing hard foreign object...

  The Risk Assessment Committee (RAC), in its final opinion, and the Socio-Economic Analysis Committee (SEAC), in its draft opinion, support an EU-wide restriction, subject to specific derogations, on the manufacture, placing on the market and use of PFAS. The Committees also recommend that any restriction should be complemented by effective measures to minimise emissions. The scientific conclusions of RAC and the draft opinion of SEAC mark a major step toward EU-level measures on PFAS. Today’s publication also launches the 60-day consultation on SEAC’s draft opinion, with stakeholders invited to submit comments until 25 May. RAC final opinion RAC concludes that PFAS pose growing risks to people and the environment. They are highly persistent, remaining in the environment for long periods, travelling long distances, contaminating groundwater and soil, while some cause serious health issues, such as cancer and reproductive harm. The Committee considers ...

ATC Manufacturing (ATC) has been awarded a contract from the Air Force Research Laboratory ( #AFRL ) for a program titled “𝗧𝗵𝗲𝗿𝗺𝗼𝗽𝗹𝗮𝘀𝘁𝗶𝗰 𝗖𝗼𝗺𝗽𝗼𝘀𝗶𝘁𝗲𝘀 𝗳𝗼𝗿 𝗟𝗮𝗿𝗴𝗲 𝗛𝗶𝗴𝗵-𝗥𝗮𝘁𝗲 𝗔𝗶𝗿𝗰𝗿𝗮𝗳𝘁 𝗦𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲𝘀.” At the center of this capability expansion is the use of a new large-format hydraulic press engineered specifically for high-rate thermoplastic processing capable of forming parts up to 122 inches (~10’ feet) x 61 inches (~5’ feet), significantly expanding the possibilities for next-generation defense and commercial platforms. This contract marks a strategic expansion of ATC’s footprint in #defense applications, reinforcing its role as a key partner in next-generation aerospace structures. The initiative will demonstrate high-rate manufacturing of #thermoplasticcomposite primary and secondary #aircraftstructures that reduce cost and upgrade legacy metallic and thermoset aerospace parts currently used in U.S. defense systems. A...

Syensqo, a leading global supplier of advanced materials and chemical solutions, has announced its participation in Semicon China at Shanghai New International Expo Centre (SNIEC) from March 25 to 27. The group will present its latest material innovations enabling next-generation #semiconductor manufacturing, with a focus on its broad portfolio of high-performance materials. Syensqo will showcase its portfolio of products at booth T0335, including its breakthrough Tecnoflon FFKM NFS range. The new portfolio has recently expanded beyond Syensqo’s market-first NFS FFKM resins for dry processes to include products designed for unmatched performance in the types of plasma and very high temperature conditions that are required for leading edge chip production. Dry Process Grades: The industry’s first commercial FFKM made without the use of fluorosurfactants, offering robust sealing and broad chemical compatibility. Plasma Resistant Grade: Resistant to degradation in fluorine,...

Today's KNOWLEDGE Share The glass transition temperature (Tg) is a key parameter in polymer science because it marks the shift from a rigid, glassy material to a softer and more flexible state. Tg helps describe mechanical behavior, processing limits, and overall performance. This infographic presents several factors that can influence Tg, including molecular structure, intermolecular interactions, and others. These trends apply to many polymers, but some systems may behave differently depending on their chemistry, morphology, and formulation. Tg provides valuable insight into how a polymer will respond, but it should always be considered within the context of the entire material system. source : Roberto Yanez

For more than 10 years, Daher has been investing in mastering thermoplastic composites to meet the requirements of aeronautical programs, including structural weight reduction, lower carbon footprint and high-rate production. The 2026 JEC Award won in the Aeronautics (Parts) category for its highly loaded thermoplastic wing rib, illustrates this expertise. Today, the #DaherGroup is taking a new step forward by structuring a complete upcycling value chain, from scrap collection to reintegration of the material into production. The objective is to reintroduce these materials into new manufacturing cycles, delivering both environmental benefits and enhanced industrial sovereignty. Upcycling thermoplastic scrap: An industrialized technical material The first pillar of this strategy focuses on #upcycling scrap that is generated during the production of thermoplastic composite parts. Working closely with its Saint-Aignan-de-Grandlieu plant (in France’s Loire-Atlantique region) and its Shap...

𝐓𝐨𝐝𝐚𝐲'𝐬 𝐊𝐍𝐎𝐖𝐋𝐄𝐃𝐆𝐄 𝐒𝐡𝐚𝐫𝐞 What Common Issues Does Blow Molding Experience? Now that you know how blow molding works to create the desired shape and some of its common products, it’s time to look at some of the issues that can be experienced during the blow molding process and what causes them 𝟭. 𝗟𝗲𝗮𝗸𝗮𝗴𝗲 Leakage occurs in the blow molding process when the gap between the blow pin nozzle and the mold is too wide. It doesn’t allow the blow pin to push enough material inside the mold, creating leaks. Leaks can also be caused by a tear in the product’s wall, contaminated plastic resin, or poor welding of the molding plastic. To prevent leakage, be sure that your blow molding manufacturer must make the blow pin nozzle and the mold a perfect match. 𝟐. 𝐑𝐨𝐜𝐤𝐞𝐫 𝐁𝐨𝐭𝐭𝐨𝐦𝐬 Rocker bottoms occur when producing bottles in the blow molding process. All bottles have a feature on the bottom known as the push-up, where the center of the bottle curves inward at va...
