This capacity expansion in Calvert City, Kentucky, strengthens the Group’s leadership in #PVDF . This investment of around 20 million US dollars will support the growing demand for #energystoragesystems and #semiconductors , as well as data center rapid expansion. Announced in February 2025, this investment has been delivered on time and within the initial budget, demonstrating Arkema’s disciplined execution and strong project management capabilities, while supporting customers’ growth. Further strengthening Arkema’s leadership in PVDF in the United States, this additional capacity will enable #Arkema to better serve fast-growing markets driven by the global energy transition and digitalization trends, where demand growth continues to materialize as expected. In particular, it will support increasing demand for lithium-ion batteries for Electric Vehicles (EVs) and Energy Storage Systems (ESS), the rapid expansion of data centers driving cable demand and infrastructure, as well as ...

SABIC, a global leader in the chemical industry, today launched its new #LNP™ELCRIN™DC0051RC1 compound, containing 75 percent post-consumer recycled ( #PCR ) content, to enhance product circularity while delivering high-performance mechanical properties. This is SABIC’s first PCR-based #carbonfiber -reinforced compound. Formulated with #polycarbonate (PC) resin, this specialty material provides excellent dimensional stability, high modulus and thin-wall #UL94V0 flame retardancy (FR), making it well suited for consumer #electronicshousings . “SABIC supports customers by developing new materials that enhance circularity,” said Sergi Monros, vice president, SABIC’s Specialties BU. “But we do more than incorporate recycled, upcycled or bio-based content in our specialty #thermoplastics . Our formulation experts also achieve high levels of performance, aesthetics and processability. For instance, our new LNP ELCRIN compound combines a high percentage of #recycledcontent with many desira...

The defect wasn't caused by the plastic. It was caused by the air. When trapped air has nowhere to escape, it becomes highly compressed. The temperature rises rapidly, and the trapped air can ignite the surrounding polymer surface. This phenomenon is known as the Diesel Effect — one of the most common causes of burn marks in injection molding. Why does it happen? ① Trapped air at the end-of-fill region ② Poor or insufficient venting ③ Excessive injection speed ④ Vent locations that cannot evacuate compressed air effectively How can it be prevented? ✓ Improve mold venting at critical end-of-fill zones ✓ Optimize injection speed to reduce air compression ✓ Design geometry that avoids air traps ✓ Validat...

As part of the CCU (Carbon Capture and Utilization) Mega Project led by Korea’s Ministry of Science and ICT, LG Chem has launched a technology demonstration project to produce e-SAF using captured carbon dioxide (CO₂) and green hydrogen.   📌 Key Highlights • Converting captured CO₂ into e-SAF • Producing next-generation sustainable fuel through CO₂ and green hydrogen synthesis • Serving as the lead organization of the CCU Mega Project from 2026 to 2030   Through this project, LG Chem aims to advance CCU technologies that transform captured CO₂ into valuable resources, improve e-SAF production efficiency and strengthen its competitiveness in carbon reduction solutions for the aviation industry. source : #LGChem

𝐓𝐨𝐝𝐚𝐲'𝐬 𝐊𝐍𝐎𝐖𝐋𝐄𝐃𝐆𝐄 𝐒𝐡𝐚𝐫𝐞 🔬 **𝐖𝐡𝐞𝐧 𝐃𝐨 𝐖𝐞 𝐑𝐞𝐚𝐥𝐥𝐲 𝐍𝐞𝐞𝐝 𝐄𝐃𝐒 𝐀𝐥𝐨𝐧𝐠 𝐰𝐢𝐭𝐡 𝐒𝐄𝐌?** SEM (Scanning Electron Microscopy) gives us beautiful images of a material's surface. It can show: • Fibers • Particles • Cracks • Pores • Coatings But sometimes the image raises a bigger question: **"What is this feature actually made of?"** This is where EDS (Energy Dispersive Spectroscopy) becomes essential. Here are some real examples: ✅ **Contamination Analysis** SEM reveals an unexpected particle. EDS identifies whether it is dust, metal debris, salt residue, or process contamination. ✅ **Coating Verification** SEM shows a coated surface. EDS confirms whether the coating elements are actually present and uniformly distributed. ✅ **Failure Investigation** SEM reveals a crack or defect. EDS helps determine whether corrosion products, oxides, or foreign materials contributed to the failure. ✅ **Filler Distribution** SEM shows particles insi...
