Thermoplastic polyurethanes LARICOL / Thermoplastic polyurethanes Thermoplastic polyurethane granules mainly used in the preparation of adhesive solutions after being dissolved in suitable organic solvents.

USAGE LARICOL are used mainly in the footwear industry where they are employed as thermoreactivable adhesives. The main advantages of these adhesives compared to the more economical types traditionally used are: high adhesive strength and good flexibility excellent resistance to oils, fats and plasticizers high adhesion to a wide range of synthetic and natural materials such as PVC, EVA, PE, leather and, after suitable pretreatment of the surface, TR, SBR good thermal resistance. In the range of LARICOL, and according to the respective application needs, one can find products that, in various proportions, present characteristics such as green strength, open time, thermal resistance and a wide range of solubility in the most common organic solvents. Therefore, can be added resins and/or inorganic fillers for improving green strength or for modifying the rheology, cross-linking agents to increase the thermal resistance, stabilizers of various types.   Specifications Products LCL1440 LCL1460 LCL1465 LCL1660 LCL2440 LCL2445 Minimum reactivation temperature   Open time   Crystallization rate   Thermal resistance   Cold resistance   Resistance to fats, oils and plasticizers               65° - 70° long low good good good 50° - 55° medium high medium medium good 55° - 60° short high low low good 50° - 55° medium medium very good medium good 65° - 70° long low good good good 70° - 75° medium medium low good good
