Advances in Reactive Hot-Melt Technology with Thermoplastic Polyurethanes Crystalline thermoplastic polyurethanes allow a high degree of control in formulating reactive hot-melt adhesives. Gonzalo Löwenberg Nicholas DeLuca January 15, 2020 Reactive hot-melt (RHM or HMPUR) adhesives are solid prepolymers terminated in reactive groups (-NCO-) manufactured from mixtures of solid and liquid polyester/ether polyols with isocyanates, which are very low in free isocyanates.Read More
