Lubrizol Advanced Materials PEARLCOAT® 125K Thermoplastic Polyurethane Elastomer
Categories:	Polymer; Thermoplastic; Polyurethane, TP; Thermoplastic Polyurethane (TPUR), Polyether Grade
Material Notes:	PEARLCOAT® 125K is a polyester based TPU, supplied in form of translucent, colorless pellets, featuring medium softening point, and consistent quality pellets, low gel content as well low-temperature flexibility. PEARLCOAT® 125K is used in a wide range of applications: Melt coatings on textile substrates, for conveyor belts, belting, among other end uses, obtained by extrusion, calendering or sintering (in this last case the product is previously ground, so as to be in powder form); Extruded films and fabric coatings; Low melting point carrier for TPU color and additives masterbatches.
