Polyols and polyurethane foams from acid-catalyzed biomass liquefaction by crude glycerol: Effects...

The effects of crude glycerol impurities on acid-catalyzed biomass liquefaction by crude glycerol were investigated. Salts (i.e., NaCl and Na2SO4) decreased biomass conversion ratios and negatively affected the properties of polyols produced. Regression models were developed and validated as appropriate for describing the relationships between...

Platelet Adhesion to polyurethane Urea Under Pulsatile Flow Conditions

Platelet adhesion to a polyurethane urea surface is a precursor to thrombus formation within blood-contacting cardiovascular devices, and platelets have been found to adhere strongly to polyurethane surfaces below a shear rate of approximately 500 s−1. The aim of the current work is to determine the properties of platelet adhesion to...

Sampling of Respirable isocyanate Particles

An advanced design of a denuder impactor (DI) sampler has been developed for characterization of possible airborne isocyanate exposure in different particle size fractions. The sampler is equipped with 12 different parallel denuder tubes, 4 impaction stages with the cut-off values (d50) of: 9.5, 4, 2.5 and 1 µm, and an end filter that collects...

Quantification of isocyanates and amines in polyurethane foams and coated products by liquid...

An analytical method for the identification and quantification of 10 different isocyanates and 11 different amines in polyurethane (PUR) foam and PUR-coated products was developed and optimized. Isocyanates were extracted and derivatized with di-n-butylamine, while amines were extracted with methanol. Quantification was subsequently performed by...
