PEARLCOAT® 125 K is a polyester-based TPU, supplied in form of translucent, colourless 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, 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).

Extruded films and fabric coatings.

Low melting point carrier for TPU colour and additives masterbatches
