Pearlstick® 45-50/18 is an elastic, linear, aromatic polyurethane, supplied in form of white spherical granules with an extremely high crystallization rate and a medium-low thermoplasticity level. APPLICATIONS: Pearlstick® 45-50/18 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. Pearlstick® 45-50/18 has a good heat resistance and improved freeze resistance, and can be used as a one-component adhesive, although the addition of a polyfunctional isocyanate improves the heat-resistance. |
