Celanese Corporation , a global specialty materials and chemical company, today announced a critical production network optimization step in support of the ‘Grow & Fortify’ strategy of its Engineered Materials business. Over the past several years, Celanese has taken significant measures to ensure reliability of supply by investing in world-class #compounding assets globally and by working to provide its customers with engineered materials products of superior quality, performance and reliability.  Today’s network optimization announcement will result in the closure of the Company’s Engineered Materials compounding facility in Ulsan, South Korea. #Celanese is planning to cease all manufacturing and production operations at the Ulsan facility immediately. The Company intends to fully support its customers to fulfill all contractual obligations and ensure a smooth transition of production and compounding activities to other Celanese manufacturing locations in the region.  ...

Huntsman Corporation announced today that it has sold Huntsman Gomet, a business located in Azeglio, Italy, to Trelleborg Group for €42.5 million (approximately $50 million), subject to customary post-closing adjustments.  Gomet is a manufacturer of molded rubber and thermoplastic automotive aftermarket components, which was a business within Huntsman's Polyurethanes division, and was acquired by Huntsman in 2014 as part of the Rockwood acquisition. In 2025, Gomet generated revenues of approximately €24 million. The proceeds from this transaction will be used to reduce outstanding borrowings. Houlihan Lokey served as financial advisor and Freshfields LLP served as legal counsel to Huntsman Corporation. source : Huntsman

Anti-Oxidant masterbatches protect the polymer chain, stabilizing it against thermal and oxidative stress. They are essential in polyolefins, engineering plastics, and films that undergo long processing cycles, ensuring durability, color stability, and consistent performance. source : Polimerizze Technology

They’re stiff and strong, helping the plant stand tall and resist wind. 🔹 Leaf fibers (like sisal & banana), act like tiny pipelines, moving water through their hollow bundles. 🔹 Seed fibers (like cotton), designed to fly with the wind. These light, fluffy fibers help the seeds travel far. 🔹 Fruit fibers (like coconut coir), serve as natural cushions. Their sponge-like structure protects the seed when the fruit hits the ground. When we understand what each fiber does in nature, we can: Decode its structure 🧬 Know where it works best 💡 Pick the right way to extract and use it 🔧 source : Mohamad Midani #naturalfibers #bioeconomy #sustainability

They’re especially critical in resins like PVC, but also used in polyolefins and other thermoplastics when changes in the mechanical behavior is needed. What They Actually Do? Plasticizers work at the molecular level. They reduce the intermolecular forces between polymer chains, lowering the glass transition temperature (Tg) and viscosity of the molten plastic. This increases the mobility of macromolecules, making the material easier to shape and more flexible after cooling. They also help with processing by reducing pressure and torque, therefore also providing lower energy consumption. source : Polimerizze Technology

In cold temperatures, the O-rings became stiff and brittle. They lost the flexibility needed to seal properly. A cold launch, he realized, was not merely risky it was deadly. Months before the Challenger mission, Boisjoly warned his managers repeatedly. He wrote memos. He...
