Lubrizol Advanced Materials Pearlstick® 45-90/06 Polycaprolactone based TPU
Categories: Polymer; Thermoplastic; Polyurethane, TP

Material Notes: Pearlstick® 45-90/06 is an elastic, linear, aromatic polyurethane, supplied in form of white spherical granules with a small amount of anti-adherent in the formulation. It has a low crystallization rate and a low thermoplasticity level.

Solubility: Pearlstick® 45-90/06 is soluble in Acetone, Methyl Ethyl Ketone (MEK), Cyclohexanone, Dimethyl Formamide, and Tetrahydrofurane (THF). 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 figures can vary, depending on the stirring process and on the solvent/diluents ratios

Applications: Pearlstick® 45-90/06 is used for the production of adhesives for different kinds of materials such as leather, textiles, rubber and a variety of plastics (plasticized PVC, PU elastomers, etc.). Pearlstick® 45-90/06 enables the production of adhesives with a very long open-time, which can be used as one- or twocomponent adhesives. The addition of a polyfunctional isocyanate to improves the heat-resistance and the strength of the joints. The addition of Pearlstick® 45-90/06 to other different types of Pearlstick® increases their open-times.
