Kolkata-based #HimadriSpecialityChemical may soon become the first company in India to set up a #carbonnanotube (CNT) manufacturing unit, said company’s CMD and CEO Anurag Choudhary. “We have successfully developed indigenous carbon nanotube (CNT) technology through our in-house innovation and R&D, marking another milestone in our innovation journey,” Choudhary said. “Backed by a planned capex of around Rs 70 crore, our upcoming 200 TPA (tonnes per annum) CNT facility, targeted for commissioning in Q4FY27 in Bengal, is expected to place Himadri among a small group of global manufacturers serving this high-growth market. This will be a pilot plant, and once stabilised, we will expand,” he said. Carbon nanotube, according to Choudhary, is a next-generation material used in #lithiumionbatteries , #electronics , #semiconductors , conductive films, sensors, #advancedcomposites , #coatings , construction and aerospace, and is expected to benefit from strong global demand. #CNT is now ...

When it comes to bi-material injection molding, Silicone (LSR) and TPU (Thermoplastic Polyurethane) are two popular options, but they offer very different advantages. 🧪 Silicone (LSR) ✅ Excellent resistance to extreme temperatures ✅ Outstanding flexibility and long-term durability ✅ Biocompatible and ideal for medical, healthcare, and food-contact applications ✅ Superior UV and weather resistance ⚠️ Considerations: • Requires specialized LSR injection molding equipment • Higher processing complexity and tooling requirements • Longer development and validation process 🛡️ TPU ✅ High abrasion and tear resistance ✅ Excellent impact absorption ✅ Recyclable as a thermoplastic ✅ Faster processing cycles and ...

When plastics are recycled, the various colours mix to create dark, low-value materials in a process known as downcycling. Conventional recycling methods cannot effectively separate colourants from plastics. Alternatively, chemical decomposition methods to remove colourants exist, but they require high temperatures of 300–500°C and lead to substantial energy consumption. These limitations thus present a growing need for upcycling technologies that enable efficient separation of colourants under milder conditions and allow plastics to be repeatedly reused as high-quality materials. In search of a solution, a research team led by Associate Professor Kenji Okada and Professor Masahide Takahashi from Osaka Metropolitan University’s Graduate School of Engineering, in collaboration with #FujiPigmentCoLtd ., developed a novel approach using #silicamicrospheres to encapsulate #colourants utilising a spray-drying method. Silica, a primary component of sand and glass, is highly resistant to he...

As packaging and industrial applications become more complex, manufacturers need reliable ways to combine materials that do not naturally bond well together. MODIC™ is an adhesive and easy-peel sealant resin designed to provide adhesion across a wide range of materials, including PE, PP, EVOH, PA, PET, metals, and glass. Used as a tie layer or peelable sealant, it gives manufacturers greater flexibility when developing structures with different functional requirements. 𝗠𝗢𝗗𝗜𝗖™ 𝘀𝘂𝗽𝗽𝗼𝗿𝘁𝘀: • 𝗠𝘂𝗹𝘁𝗶𝗹𝗮𝘆𝗲𝗿 𝗽𝗮𝗰𝗸𝗮𝗴𝗶𝗻𝗴: Films, sheets, bottles, and containers that combine structural, barrier, and sealing materials within one format. • 𝗙𝗹𝗲𝘅𝗶𝗯𝗹𝗲 𝗽𝗮𝗰𝗸𝗮𝗴𝗶𝗻𝗴: Tie-layer and sealant applications for blown films, cast films, extrusion lamination, and easy-peel lidding. • 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗮𝗹 𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲𝘀: Multimaterial components, coated pipes, composite panels, and other applications where strong adhesion between different substrates is required. •...

New bio-based, crush-and-sniff floor mat brand debuts July 14 with six bold shapes and scents priced at $19.99 CRUSH!, a new consumer lifestyle brand, officially launches today with a floor mat you crush to release fragrance. They will be available on July 14 at $19.99 each, in six bold shapes and signature scents. CRUSH! is designed for those who want something that’s fun, smells great, and is worth posting about. Unlike traditional air fresheners, CRUSH! mats are 17” x 22” in size and live on the floor of your car (passenger side only!), dorm room, bathroom, or gym bag and release scent on contact every time they’re stepped on or crushed. The six launch designs span fruits (cherry, strawberry, and watermelon) and objects (lucky cat, rubber duck, and luchador mask) each with its own personality and a matching signature scent (among which are fun scents like orange creamsicle, strawberry cheesecake, and pink watermelon lemonade, to name a few). Every mat is made from 100% bio-based, fu...

𝐓𝐢𝐧𝐮𝐯𝐢𝐧® 𝐍𝐎𝐑-𝐇𝐈𝐆𝐇 𝐔𝐕 𝐑𝐄𝐒𝐈𝐒𝐓𝐀𝐍𝐂𝐄 in MULCH FILM APPLICATIONS From Barcelona to Gujarat, Jordi Espinos went the extra mile, quite literally, to see how mulch films perform where it matters most: laid out in the field and exposed to the sun. During his visit to a farm in Gujarat, western India, Jordi walked through fields where mulch films were laid out across the farm to better understand the local challenges film makers and farmers face in India’s demanding agricultural environment. With intense sunlight, high temperatures, acidic microclimates, and increasingly aggressive agrochemicals, mulch films need to do more than protect crops for one season. They need to stay durable, stable, and reliable across repeated growing cycles. That is where Tinuvin® NOR® comes in. Designed to support high UV resistance and improved agrochemical stability, Tinuvin® NOR® helps mulch films deliver multi-season performance, reducing replacement needs, labour effort, and plastic was...
