Lubrizol Advanced Materials PEARLCOAT® 126K Thermoplastic Polyurethane Elastomer (discontinued **)
Categories:	Polymer; Thermoplastic; Polyurethane, TP; Thermoplastic Polyurethane (TPUR), Polyether Grade
Material Notes:	PEARLCOAT® 126K is a polyester-based TPU, supplied in form of translucent, colorless pellets, combining hardness with excellent low temperature flexibility and medium softening point. PEARLCOAT® 126K is used in 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). PEARLCOAT® 126K is used for obtaining extruded films and fabric coatings. All information provided by Merquinsa
