Celanese Corporation, a global specialty materials and chemical company, and Röchling Industrial, a leading global plastics processor and part of the Röchling Group, today announced a collaboration regarding use of lower-carbon #polyoxymethylene (POM) solutions in stock shape applications. Under the collaboration, Röchling Industrial has procured Celanese #POMECO -C for use in selected stock shape applications, supporting Röchling Industrial’s continued focus on increasing sustainability. The patented Celanese process uses Carbon Capture and Utilization ( #CCU )-based chemical building blocks to turn CO2 emissions into high-performance POM polymer that offers both reduced product carbon footprint (PCF) while incorporating circular feedstock content through a mass balance approach. Designed for straightforward adoption, the POM ECO-C grades manufactured by Celanese enable customers to choose more sustainable materials across a wide range of uses without compromising critical POM proper...

Medical monitoring patches, wearable sensors, flexible diagnostic devices, and touch interfaces on non-planar surfaces are the contexts it is designed for. 𝗧𝗵𝗲 𝗰𝗵𝗮𝗹𝗹𝗲𝗻𝗴𝗲 in these applications is not simply achieving electrical conductivity. The ink must adhere reliably to unconventional substrates, maintain its electrical performance under bending and deformation, and in medical contexts, meet the biocompatibility requirements that apply to materials in contact with skin or used in #diagnosticdevices . The graphene-based formulation is optimised to meet these constraints simultaneously, in a form that is compatible with standard #printingprocesses . Potential applications...

LG Chem is poised to expand its presence in the European mobility market by showcasing its high-value materials portfolio for future vehicles.   LG Chem announced today that it will participate in the International Suppliers Fair (IZB 2026), to be held Oct. 27―29 in Wolfsburg, Germany. IZB is a premier biennial global trade fair for automotive suppliers and component manufacturers. Originally a supplier showcase for the Volkswagen Group, it has grown into a leading international event where major suppliers and global parts and materials companies network to explore new business opportunities. This year’s exhibition is expected to draw about 850 companies from 33 countries and more than 40,000 visitors.   LG Chem is participating in IZB for the first time and will be the only Korean materials company at this year’s event. This debut follows the signing of a Memorandum of Understanding (MoU) with the Volkswagen Group in September to jointly develop future mobility materials, mar...

𝐌𝐚𝐭𝐞𝐫𝐢𝐚𝐥𝐬 𝐒𝐜𝐢𝐞𝐧𝐜𝐞 : 𝐀𝐝𝐯𝐚𝐧𝐜𝐢𝐧𝐠 𝐇𝐲𝐝𝐫𝐨𝐠𝐞𝐧 𝐁𝐚𝐫𝐫𝐢𝐞𝐫 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞 Type IV composite cylinders typically integrate a polymer liner for gas containment with a fibre-reinforced composite overwrap that carries the primary structural loads. The challenge is to develop liner materials that minimise hydrogen permeability without compromising mechanical properties, processability, dimensional stability, or long-term durability. Several promising research and development directions are attracting attention: 𝟏. 𝐀𝐝𝐯𝐚𝐧𝐜𝐞𝐝 𝐩𝐨𝐥𝐲𝐦𝐞𝐫 𝐥𝐢𝐧𝐞𝐫 𝐟𝐨𝐫𝐦𝐮𝐥𝐚𝐭𝐢𝐨𝐧𝐬 Optimising polymer chemistry, morphology, and processing conditions may help reduce hydrogen permeability while maintaining the mechanical properties required for demanding service conditions. 𝟐. 𝐍𝐚𝐧𝐨𝐜𝐨𝐦𝐩𝐨𝐬𝐢𝐭𝐞 𝐛𝐚𝐫𝐫𝐢𝐞𝐫 𝐭𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐢𝐞𝐬 Selected nanofillers may increase the tortuosity of diffusion pathways within a polymer matrix. However, their effec...

In injection molding, the cavity is typically filled to only 95–98% capacity during the injection phase. The packing phase then pushes additional material into the cavity to compensate for volumetric shrinkage as the plastic cools. Holding pressure serves a distinct, subsequent function: it maintains equilibrium pressure to prevent molten material from flowing back out before the gate freezes. As Suhas Kulkarni of FimmTech explains, the practical distinction depends on gate geometry and system type: - Small gates (0.040 in. or less) freeze quickly, making a combined pack-and-hold phase acceptable - Larger gates and hot runner systems require separate pack and hold phases - Valve-gated molds require only a packing phase — holding pressure ...
