Lubrizol Advanced Materials Pearlstick® 45-60/14 Polycaprolactone based TPU

Pearlstick 45-60/14 is an elastic, linear, aromatic polyurethane, supplied in form of white spherical granules with an extremely high crystallization rate and a low thermoplasticity level.Solubility: Pearlstick 45-60/14 is soluble in Acetone, Methyl Ethyl Ketone (MEK), Cyclohexanone, Dimethyl formamide, (DMF), Tetrahydrofurane (THF). Diluting solvents such as Toluene and Ethyl Acetate can be added. The solvents and diluents should be water-free (max. 0.1%), so as to avoid subsequent side reactions during crosslinking with isocyanate. Pearlstick 45-60/14 should be dissolved in closed tanks and the use of high shear equipments is advisable. The final viscosity fies can vary, depending on the stirring process and on the solvent/diluents ratios. Applications: Pearlstick 45-60/14 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. The adhesives based on Pearlstick 45-60/14 show. High green strength values. Easier heat activation (wide range of activation temperatures). Long and high hot-tack (tack retention). Pearlstick 45-60/14 may be suitable as a raw material for the production of one-component adhesives.Information provided by Merquinsa
