BARCELONA, Spain -- Lubrizol Advanced Materials M.S. S.L. (FKA Merquinsa) announces it will be presenting a new, fast, high heat TPU (thermoplastic polyurethane) material development for hot melt adhesives (HMAs) at the FEICA European Adhesive and Sealant Conference and Expo in Vilamoura, Portugal from September 9-11.

Lubrizol has developed a new thermoplastic polyurethane (TPU) for high performing HMAs used in diverse markets like footwear, automotive, filtration, apparel interlinings, textiles, sports goods and packaging. Until recently, materials used in these applications were limited to copolyamides and copolyesters to achieve a good initial adhesion in a few seconds and high-heat resistant performance. Thanks to Lubrizols industry-leading formulation technology, a new material with elastomeric features has been launched that outperforms traditional materials based on its polyurethane chemistry. This new, fast, high-heat material adds improved impact resistance, adherence (higher polarity) and vibration absorption vs. competitive materials.

"This new, unique TPU solution provides a higher life cycle expectation due to its toughness at lower temperature cycles and its lower glass transition," states Gonzalo Lowenberg, global R&D manager for adhesives applications & technical service, Estane Engineered Polymers. "Now, thanks to the solution formulated by Lubrizol, there is a revolutionary new crystalline TPU chemistry that has broken the barriers of the traditional TPU adhesive market."

Lubrizols Pearlstick) and Pearlbond) TPU product lines for adhesives includes polymers that can be utilized in hot melts, solvent-based adhesives, HMPUR (or RHM - Reactive Hot Melts) and adhesive films.
