PEARLCOAT® 127K is a polyester-based TPU, supplied in form of translucent, colourless pellets, combining hardness with excellent low temperature flexibility and medium softening point. PEARLCOAT® 127K is used in melt coatings on textile substrates for conveyor belts, belting, etc. end uses, obtained by extrusion, calendering or sintering (in this last case the product is previously ground, so as to be in powder form). |
