Pearlstick 104 Polyester based thermoplastic polyurethane Merquinsa PU - Thermoplastic (TPU) ADHESIVE FOOTWEAR & LEATHER The PEARLSTICK® ranges are thermoplastic polyurethanes elastomers (TPUs) specially developed for use as raw material in the manufacture of toe puffs & counters(shoe industry). The PEARLSTICK® grades are supplied in pellet form and can be applied by extrusion process (T-die) or sintering (in such case they must be previously cryogenically ground). PEARLSTICK 104 is an elastic, linear, aromatic polyurethane with a high crystallization speed and a high thermoplasticity level. PEARLSTICK 104 is used for textile coating for making shoe-stiffeners (toe-caps, counters), by sintering process. high thermoplasticity high crystallization rate Elastic, linear, aromatic polyester-based thermoplastic polyurethane. Used as a raw material in manufacture of toe puffs and counters (shoe industry). Possesses high crystallization rate and thermoplasticity.
