Dust, oils, moisture, and release agents can act as invisible barriers between the adhesive and the substrate. Even small amounts of contamination can dramatically reduce bond strength. This is why surface preparation is so important in many industrial applications. Cleaning a surface may seem like a small step, but it can completely change adhesion performance. When bonds fail unexpectedly, contamination is often the hidden cause. Before redesigning the adhesive, it’s worth examining the surface. Sometimes the simplest explanation is the correct one.

Borouge Group International AG (“Borouge International”) today announced that, following the successful completion of performance testing, it has delivered the first batch of materials from its new #CrossLinkedPolyethylene ( #XLPE ) plant in the #UAE to customers in the region. The new XLPE plant adds 100,000 tonnes of annual capacity, doubling Borouge International’s current XLPE output in the Middle East and Asia region per year. XLPE is used in high-voltage underground and underwater #powercables that support grid expansion, electrification, and the transformation of energy systems. Borouge Plc, part of #BorougeInternational , operates the region’s only XLPE plant of its kind, strengthening its ability to meet rising demand from fast-growing economies and data centers across Asia and the Middle East. Borouge International collaborated with Ducab, a leading UAE-based end-to-end energy solutions provider and manufacturer of high-quality #cables and #wires , to successfully test th...

Avantium N.V., a leader in renewable and #circularpolymermaterials , today announced a strategic partnership with #SojitzPla -Net Corporation to drive the adoption of Avantium's plant-based materials FDCA and PEF (marketed under the #releaf® brand), in the Japanese market. The partnership combines Avantium’s innovative technology with Sojitz Pla-Net’s extensive commercial network and expertise in plastics, packaging materials and sustainable solutions. As one of Japan’s leading plastics trading companies and part of the Sojitz Group, Sojitz Pla-Net will support market development and customer engagement for releaf® across Japan, while also exploring opportunities to jointly develop business with customers and partners in international markets. FDCA ( #furandicarboxylicacid ) is a plant-based building block for the production of PEF ( #polyethylenefuranoate ), Avantium’s flagship polymer marketed under the releaf® brand. PEF is #plantbased , recyclable and offers superior barrier p...

However, excessive injection pressure can significantly reduce the lifespan of a mold if its components are not properly designed and locked. ⚙️ At Star Moldes, we pay close attention to every locking and supporting element to ensure the mold withstands production demands over millions of cycles. 🔩 💡 Some mold types are especially susceptible to damage caused by high injection pressures: 🔹 𝐌𝐨𝐥𝐝𝐬 𝐰𝐢𝐭𝐡 𝐬𝐥𝐢𝐦 𝐨𝐫 𝐥𝐨𝐧𝐠 𝐜𝐨𝐫𝐞𝐬, 𝐰𝐡𝐞𝐫𝐞 𝐝𝐞𝐟𝐥𝐞𝐜𝐭𝐢𝐨𝐧 𝐜𝐚𝐧 𝐨𝐜𝐜𝐮𝐫. 🔹 𝐌𝐨𝐥𝐝𝐬 𝐰𝐢𝐭𝐡 𝐭𝐡𝐢𝐧 𝐜𝐚𝐯𝐢𝐭𝐲 𝐢𝐧𝐬𝐞𝐫𝐭𝐬 𝐭𝐡𝐚𝐭 𝐫𝐞𝐪𝐮𝐢𝐫𝐞 𝐚𝐝𝐝𝐢𝐭𝐢𝐨𝐧𝐚𝐥 𝐬𝐮𝐩𝐩𝐨𝐫𝐭. 🔹 𝐔𝐧𝐬𝐜𝐫𝐞𝐰𝐢𝐧𝐠 𝐦𝐨𝐥𝐝𝐬 𝐨𝐫 𝐦𝐨𝐥𝐝𝐬 𝐰𝐢𝐭𝐡 𝐦𝐨𝐯𝐢𝐧𝐠 𝐦𝐞𝐜𝐡𝐚𝐧𝐢𝐬𝐦𝐬, 𝐰𝐡𝐞...

Research team at #RochesterInstituteofTechnology (RIT) in New York, US, is working on a plant-derived material that could replace certain plastic uses in packaging. The work centres on starch, which is being adapted into a #biopolymer layer for paper-based packaging. The project is led by Sneh Bangar, assistant professor of packaging science in RIT’s College of Engineering Technology and leads the  #foodpackaging and shelf-life testing laboratory. Bangar said: “We were able to achieve the same barriers that #plasticlamination or plastic coatings give. The goal is not to eliminate plastics but to reduce the use of plastics. “When it comes to packaging, the food category contributes the most to the need for packaging options. We can add value to alternative packaging options with this new work. The researchers used crosslinking methods to modify pearl millet #starch and change its internal structure to improve the material’s viscosity and make it more stable. Crosslinking is a chemi...
