Lubrizol Advanced Materials Pearlstick® D40-70/03 Linear Thermoplastic Polyurethane

Pearlstick D40-70/03 is an elastic, linear, aromatic polyurethane, supplied in form of white spherical granules with an extremely high crystallization rate and a very low thermoplasticity level. Solubility: Pearlstick D40-70/03 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 D40-70/03 gives transparent solutions. It they 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: A safety data sheet on Pearlstick D40-70/03 is available, with all safety information. When solutions are prepared, the usual safety practices in the handling of chemicals should be observed, i.e.: good ventilation in the working area, good skin protection and protective goggles.Information provided by Merquinsa
