Lubrizol Advanced Materials Pearlstick® 46-10/16 Polyester based TPU

Pearlstick 46-10/16 is an elastic, linear, aromatic polyurethane, supplied in form of white spherical granules with a very high crystallization rate and a high thermoplasticity level. Solubility: Pearlstick 46-10/16 is soluble in Methylene chloride, Acetone, Methyl Ethyl Ketone (MEK), Ethyl Acetate and Tetrahydrofurane (THF). Diluting solvents such as Toluene can be added in large amounts. The solvents and diluents should be water-free (max. 0.1 %), so as to avoid subsequent side reactions during crosslinking with isocyanate. It should be dissolved in closed tanks, and the use of a variable speed agitator is advisable. The final viscosity fies can vary, depending on the stirring process and on the solvent/diluents ratios Applications: Pearlstick 46-10/16 is used for the production of adhesives for plasticized PVC to plasticized PVC or other materials such as leather, textiles, metals, paper, etc. in the shoe and furniture industry. The addition of a polyfunctional isocyanate to improves the heat-resistance and the strength of the joints.Information provided by Merquinsa
