Lubrizol Advanced Materials Pearlstick® 46-10/01 Linear Thermoplastic Polyurethane Elastomer

Pearlstick 46-10/01 is an elastic, linear, aromatic polyurethane with a very high crystallization rate and a very high thermoplasticity level, available as pellets.Solubility: Pearlstick 46-10/01 is soluble in methylene chloride, acetone, methyl ethyl ketone (MEK), ethyl acetate and tetrahydrofuran (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 isocyanates.Solutions: Pearlstick 46-10/01 should be dissolved in closed tanks, and the use of a variable speed agitator is advised. The final viscosity fies can vary, depending on the stirring process and on the solvent/diluents ratios.Applications: Pearlstick 46-10/01 is used for the production of adhesives for bonding plasticized PVC to plasticized PVC or other materials such as leather, textiles, metals, paper, etc.Pearlstick 46-10/01 enables the production of adhesives with high solids content and low viscosity, which are adequate for application in the wood and shoe industries. The addition of a poly-functional isocyanate improves the heat-resistance and the strength of the joints.
