Pearlstick® 48-60/19 is an elastic, linear, aromatic polyurethane, supplied in form of white spherical granules with a very high crystallization rate and a medium-low thermoplasticity level. Pearlstick ® 48-60/19 is used for the production of adhesives for bonding plasticized PVC to plasticized PVC or other materials such as leather, textiles, rubber, in the shoe industry. The addition of a polyfunctional isocyanate improves the performance of the adhesive. |
