Lubrizol Advanced Materials Pearlstick® 46-10/12 Polyester based TPU

Pearlstick 46-10/12 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 46-10/12 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 46-10/12 is used for the production of adhesives for plasticized PVC to plasticized PVC or other materials such as leather, textiles, metals, paper, etc. It can be used in the shoe industry as an adhesion promoter in the process of injection of PVC soles to the uppers Pearlstick 46-10/12 can be used as a two-component adhesive in furniture making, since two-component adhesives are advisable for the lamination of PVC films. The addition of a polyfunctional isocyanate to improves the heat-resistance and the strength of the joints.Information provided by Merquinsa
