Epacol TK series

TPU for solvent borne adhesives

The Epacol series by Epaflex comprises products specifically developed for the processes of production of solvent-based adhesives. The TPU granules in the Epacol series by Epaflex are heat activated and, therefore, inert at room temperature. The range is available in various grades which differ in terms of viscosity, reactivation temperature, rate of crystallisation and solubility.
