Lubrizol Advanced Materials Pearlcoat® 125KW Thermoplastic Polyurethane Elastomer (discontinued **)
Categories:	Polymer; Thermoplastic; Polyurethane, TP; Thermoplastic Polyurethane (TPUR), Polyester Grade
Material Notes:	Pearlcoat® D125KW is a polyester-based aromatic TPU, supplied in form of white-colored pellets, combining hardness with excellent low-temperature flexibility. Applications: Pearlcoat® D125KW is used to melt coatings on textile substrates for conveyor belts, obtained by sintering (in this case the product is previously ground, so as to be in powder form). For optimum results, previous drying of the product for 2 hours at 90 - 100°C is advisable, in a hot air circulatory, vacuum or desiccant-air dryer.
