Covestro completed the acquisition of two former Vencorex production sites for HDI derivatives in Rayong, #Thailand , and Freeport, Texas, USA. With the acquisition, #Covestro expands its production footprint for #HDI derivatives and reaffirms its commitment in two important regions, while strengthening its ability to serve customers in the #coatings and #adhesives industry with greater flexibility and reliability. HDI derivatives are essential building blocks for high-performance polyurethane coatings, adhesives and sealants. They are used in a broad range of applications, including automotive coatings, protective coatings for infrastructure, marine coatings, wood furniture, electronics and other demanding industrial applications. “By adding these sites in Thailand and the US, we are strengthening our regional production capabilities and improving our ability to supply customers from locations close to them,” said Thomas Roemer, Head of the Business Entity Coatings and Adhesives a...

License agreement to deploy Syensqo’s DDF technology and jointly qualify innovative materials for OEM part production #Syensqo , a leading global supplier of advanced materials and chemical solutions, today announced a partnership with Bucci Composites, a leader in the design and manufacture of structural composite parts, including a license for Syensqo’s Double Diaphragm Forming (DDF) technology.

The technology helps reduce total cost of ownership by simplifying logistics, improving part accuracy, and optimizing capital investment through integration with existing manufacturing infrastructure.    Building on decades of collaboration between t...

 𝐓𝐨𝐝𝐚𝐲'𝐬 𝐊𝐍𝐎𝐖𝐋𝐄𝐃𝐆𝐄 𝐒𝐡𝐚𝐫𝐞 👋💡 𝐓𝐲𝐩𝐞𝐬 𝐨𝐟 𝐀𝐜𝐫𝐲𝐥𝐢𝐜 𝐑𝐞𝐬𝐢𝐧𝐬⚙️ Acrylic resins are generally divided into two main categories, and based on these categories any resin type can be classified: Thermoplastic and Thermosetting. To prepare a resin from either category, the polymer must be converted into a solution, meaning that the polymer is dissolved in an organic solvent. The monomers—such as MMA, BA, or EA—are polymerized and then dissolved in an organic solvent to form the solution. 🥇Thermoplastic Solution Acrylics (TPAs) This type is a copolymer, made from different monomers that build long polymer chains, which gives it a high molecular weight. This type does not use crosslinkers 🛠️to form a network structure, because the film forms simply through the entanglement of the long polymer chains⛓️. TPAs cure at ambient temperature without the need for any crosslinkers. Because of their high molecular weight, they form a film by solvent evaporation. Th...

For decades, PVC has been one of the most widely used materials in construction and industrial applications. As industries continue to demand higher durability, improved heat resistance and longer service life, material innovation has become increasingly important. That challenge inspired the development of HRTP4000, LG Chem’s Ultra-high Molecular Weight PVC. By increasing the degree of polymerization to over 4,000—more than four times that of conventional PVC—and combining it with LG Chem’s proprietary processing technology, HRTP4000 achieves a unique balance of high mechanical performance and excellent processability. Why HRTP4000? ✅ Ultra-high Molecular Weight ✅ Degree of polymerization exceeding 4,000 for enhanced mechanical performance. ✅ Patented Processing Technology ✅ Proprietary technology enables ultra-high molecular weight while maintaining excellent processability. ✅ Enhanced Durability ✅ Improved wear resistance, heat resistance and long-term reliability for demanding appl...
